Could it be happening when you close a door and the air flow that that often causes?
Try a bit of Blu Tac and fasten it to the surface. If it's a polter, see how it copes with that. If it still moves, you know you might have a bit of a problem.
No, I don't think so. I think it's been happening for months maybe years without me realising.
It's a good thought, but that doesn't seem to be the case.
I'll look out for that, but I tend to leave the door slightly open if anything to be honest.
I'm going to try it on a different surface today and see what happens then. If it still moves I will try the Blue Tac tip.
Maybe the pizza place next to the stop is naff and the other one serves his fave pizzas or he works there. Or was the pizza box carrying something other than a pizza and was used as a disguise
Maybe just trying to gaslight passers by?
We never did it but a friend of mine I used to go hillwalking with always said we should take all our food up to the top of the hill in McDonalds containers and tell people there was one just over the hill. 
That's really very naughty!Maybe just trying to gaslight passers by?
Or - pizza boxes in one region all generally come from the same supplier. I have known stores that didn't care that bought overage bags and boxes at a discount that had someone else's name on them, or bought some cheap and held them for emergencies. The pizza did not necessarily come from the store with the name on the box. On a tangent, I have been told by someone familiar with the industry that ALL Chinese restaurant supplies in the US come from one of two suppliers, one east of the Mississippi and one west . Which explains why all of the restaurants on your state have the same containers and the same menus. I also worked with someone whose husband printed the menu's for the eastern supplier. Enterprise at its best.
No, that would be 'Starve Trek' - doth anyone remember it?
All of these are reasonable explanations, except I happened to pass by the place around noon the next day and they had a HUGE supply of their own boxes in that size. I suppose they had a few of the other store's on hand that they wanted to get rid of, or they just got the new boxes in that morning and had time to assemble them, but I doubt it.
I didn't eat pizza at all until I was 28, because it had cheese on it (and I really hate cheese).I tried pizza once as a kid and decided I hated it - think it was the savoury pastry that was so horrible, rather than the filling. I tried it a second time in my 30's and it actually wasn't too bad, tastebuds had obviously changed over time.
30 minutes later I had a tummy ache, as if I eaten something that didn't agree with me.
I don't know what that is, but it ain't pizza, I don't care what it says on the box.
I really dislike the bases of pizza so this would suit me perfectly.
Sounding better by the minute.
So, Mytho hates cheese and you hate pizza bases? (Unless you're referring to those crappy frozen ones, in which case I would agree with you), I think you've both gone quite insane!
I hate to say it, but I'm not that keen on bread. And pizza bases are always too doughy and bready for me. Oh, and I don't like tomato sauce either. So, basically, I'm here for the cheese.
Try pizza in Italy... the pizzas I have eaten in Naples and Positano are the best I've ever eaten, they are a different beast entirely and cannot remotely be compared with UK pizzas.
Oh yes, I'd probably like those. But stuck in Yorkshire, the opportunity for tasty pizza is....limited, shall we say.
It did occur to me that you might appear with a liking for a cauliflower based pizza, with maybe a brussels sprouts and broccoli topping.
Shudder. Abomination. We need a pizza inquisition urgently.
Calm down, nobody's mentioned... pineapple!
Nobody expects that!
