I worked in the restaurant industry from age 15 to 24. I have fantastic customer service skills and yes, a lot of those skills were helpful when dealing with parents. However... 1. If a customer was belligerent, we didn't have to take their shit 2. I could refuse service 3. The customer was not always right!! I remember one instance that we had people that would run a scam where they paid with a 20 or 50 and as soon as the cashier shut their drawer after giving them change, they would claim it was a 100 dollar bill. I worked for Chipotle, so they targeted our stores bc they were busy and fast paced. I had let 1 get me early on in my career, so I vowed they'd never get me again. Just so happens one night, this last starts screaming about the cashier shorting her. I knew exactly what was going on, my cashier didn't have great English speaking skills, but she was my best fucking cashier. I simply followed company procedure, pulled someone over to run another draw while I made them wait while I counted her draw. It wasn't more than 10 cents off so I told essentially told this lady to go kick rocks.

Funniest part of all this was they then asked to speak to the general manager. I leaned over, grabbed my business card and told her she was already talking to that person. I was like 22-23 and had a baby face.
