In 2017, I worked at an amusement park for about 4 months and got experience working as a cashier and at multiple different restaurants and other food/drink service locations in the park such as Tim Hortons, an ice cream truck, pizza pizza, drink stations, etc.
But then, so unfortunately, one day, close to the end of my term working at the amusement park for the summer, when I was working at a drink station, a customer gave me $5 and because my cash register was already closed, I thought it was a tip and pocketed it. You don't have to believe this story, but honestly it's what I thought and it was a mistake that could happen to me after doing over 200 transactions in one day and being someone with ADHD. A surveillance worker witnessed this, and long story short I got fired.
Is it possible for me to use this somehow on my resume to prove that I have experience working as a cashier and at tim hortons and pizza to get such jobs? Or should I keep it off my resume forever?
