I work access control at a data center for a multi-national bank. Have you been a sh*tty employee recently? Prepare to no longer have access to random doors in the building, and that will change as the day goes on. - WadeNotSlade

I make their sandwiches with a little extra mayo or sauce and then I squeeze it as I wrap it up. - Sexyazzwife

Manager at domino's. We usually will just blacklist the number if they try to complain too much. As managers we can totally push back in a formal and calm manner. If you have a genuine complaint then we'll give you reimbursement but if it becomes a regular thing then we will blacklist you and you can no longer order from us - yung-sprout
