We have one chocolate bars salesman (first year at school) who seems to know everyone's chocolate weakness.

When one kid asked if he had a peanut butter cocoa bar, he said "Yeah, I have one left though.". Kid didn't have money, I offered to buy and he would pay back, but his friend bought that one and the guy said "I have a milk chocolate with dark chocolate drizzle too." The friend loves those, he bought them. Since I had the dollar out, the kid said "You know I have dark chocolate covered pretzels."

They are my weakness.
Looked at the dollar. Looked at him. Looked at the dollar. Looked at him.
Caved.

I just heard a girl say to the guy "You know I hate you so much" as he walked away from her lunch table after handing her 4 chocolate cherry bars.
