A question for my American acquaintances:

How do you handle fast food during consumption? What processes do you go through?

As a Canadian travelling for business and pleasure, I have noticed there are significant differences between table etiquette between the two regions. Mostly I am interested in the handling of take-away sandwiches (like burgers, burritos, or doners). The manner of handling "wrapped" food seems to be different.

I have tried to emulate it in the past, but have noticed my Canadian peers getting looks of disgust and not even being aware that there is a difference.
