Inspired by another thread, I admit!
I’ve been dating a long time and have had some crackers. One that really stands out is the one who turned up in a foul mood and drove like a manic to the restaurant because he was hungry!!! He seemed to think that was acceptable and said everyone was in a bad mood when hungry. It was our third date. We didn’t see each other again.
A more recent one...pre covid, we’d been for dinner and driving back to mine. He was quiet. I asked if he was ok. He said ‘need the toilet’ and farted really loudly. I was embarrassed and said thanks for dinner then he tried to kiss me.
Finally, when messaging someone online, we were chatting about what to make for dinner. In the middle of the chat he disappeared. An hour later he came back and said ‘sorry, 8pm is my toilet window and I like to stay regular. Where were we?’ 
It’s been fun.
