The toilet overflowing and sending a river (complete with "boats") into the dining room....
The employee doing something personal in a bathroom stall that was not related to going potty....Always assume someone could be in the bathroom and don't walk out with evidence very evident!
A customer passing out, hitting his head, and the staff doing absolutely NOTHING. They would not even call 911! The manager refused to come out to the dining area. I administered care until the EMT's/paramedics arrived and I could successfully do a hand off.
Then got back in line and started the timings all over again as though I had just walked in. (Emailed the scheduler about the incident and asked for guidance on the report. Got dropped from the company over this. Sorry - if someone has a medical emergency and needs help, I am going to help. If the staff couldn't be bothered to even acknowledge the incident, do you really think they are going to remember me???)
Reporting that I had paid for a very nice dinner and dessert and never received it. Yep. Server brought the wrong entrees out, when I brought it to her attention, she brought the check (complete with a dessert charged on it), waited for the cc and immediately processed it, but never brought out the correct entrees or dessert.
Hearing incredibly personal conversations about illegal activities occurring at work. Yes. For real.
Employees stealing from customers.
Does these count as awkward?
The other awkward things, but not included in reports (no specific place for this/company not interested), receiving life stories, seeing awkward photos, being told "confidential" or proprietary information, being asked out, witnessing PDA...
