re: Retailer/server employees: worst ever customer?

Worked at a small local restaurant in HS as a busboy. Couple left a stack of pennies on the table as their tip. As they walked out, they see me clearing the table and start laughing. I proceed to use my cloth to wipe the table and slam the pennies across the floor (slow day so only 1 other table at the time) then bring the pan to the back. Apparently they filed called in to file a complaint against me about 30 minutes later. Manager suggested I find another job because I'm not cut out for service industry

Worked at Sears and a guy came to the counter to return used underwear for a brand we no longer carried. Had stains, holes, stretch marks... I refused, he demanded a manager. Manager told me I had to take the return, I obliged then told her she has to bag them up and bring them to the back. She gave me I'm the manager speech, I told her if I have to do it I walk out right now (only 1 on the floor for the department). After that, I went and applied at the bank down the street
