How many people stop every day at a place like Starbucks and buy
something to eat along with thier coffee or tea. They might purchase a
muffin or cereal or anything additional to eat. I am not intersested
in fast food places like McDonalds and Egg McMuffins, but rather the
higher ticket places like Starbucks.

You should probably change your "every day" to more than 280 times (or
days/or mornings) per year, or some such, as most people do something
different when sick, on vacation, on days off from work etc  You did
not mention breakfast in the question; only in the subject. Did you
intend to not count persons who enter the resturant after 11 am, even
if they slept until 10;30 am? Do you want world wide or just the 48
states or other? Did you intend to exclude persons who have a similar
ritual, but do not always (or never) order coffee or tea?   Neil

I'll take whatever I can get for information. Be creative.
