This is a useful lesson in anonymity, too. Let's work with what the OP told us:
-Works at McDonalds (3500 stores, give or take)
-"In the ghetto" = high risk stores (500 stores).
-"It's always super dead" = lowest performing stores (200 stores)
-Win2003 + i2i (assuming it's not standard issue, some stores may have different video vendor) (100 stores)
-OP is about 18, getting GED, interested in computers.
-OP had specific interaction with manager
So with just that, you're talking maybe 100 managers being emailed about a specific interaction with a very specific person. Chances of detection are immense.
Probably 50% of people on hacking/security forums are working for corporations like McDonald's.
