Omg that was so embarrassing

I went over to an couple at work and I had no idea it was an dancer with no makeup on and I sat with them and introduced myself. Omg she looked so different and I thought she was an customer 😳😳 I apologised as I had no idea ! And I was chatting them up 😭 I feel so embarrassed. I wanted to get up so badly but the guy wanted me to stay for an bit. I went to the restroom. I got $20 for an drink but I can’t bring myself to get one now 😭 I hate it when people who work there come in as customers. She kept looking at me so I thought hey she wants an dance 😹 I’m still very new to all of this and I had no idea dancers came in sometimes as customers as most clubs don’t allow that. I have bad social anxiety so that’s mainly why I go all embarrassed very easily.
