I work in software engineering, one time I did an UPDATE sentence on the database without the WHERE clause, in production environment, without a backup (translation, I ruined 6 months worth of data)
It's not your fault they didn't have a backup and they should not allow you to access production data with ad hoc queries and especially not give you CRUD access. So I would blame them.
One time I was working the jewelry counter (I work in a department store) and I was showing someone a diamond ring while also trying to juggle a few other customers. You're only supposed to help one customer at a time especially if you're showing a diamond and you're also supposed to call the LP officer (the guy who watches the cameras and catches shoplifters) when you're showing a diamond so that they can keep an eye on the customer. Welp I was handling multiple customers AND forgot to call LP and the customer ended up slipping away with the ring. Oops lol.
When I was a waiter I accidentally spilled this woman's milkshake, as I was delivering it to her, all over her table. The glass smashed and the milkshake went everywhere. I was so embarrassed. But now it's just a funny story to tell, to me.
When I worked retail in college, there were times (when it was busy) where i'd forget to scan a few items - people buy a lot of **** on the weeknds. Sometimes the customers would say "hey, you didn't ring this up" but the majority (of course) would not notice my mishap.
