Not trolling here but wondering a few things re etiquette and acceptable tender. Recently I have found myself mainly carrying 50 notes and it has become more difficult to get 10 and 20s as many ATMs are out of service or only offering 50s. This poses a problem when it comes to meeting certain ladies who are on the 70, 80,90,110 etc scales.

Now twice I had to get change in a shop and they first thought I was a conman with fake notes but were sound after checking. Another time I paid one of the escorts an extra 10 as I had not the right amount, I looked for change but she had none but the sex was good so happy enough. Now last time I paid the last 5 of my 80 in coins as I hdsnt correct amount in notes. She said its fine its legal tender but it felt a bet cheeky doing it, I dont want to offend her

So my Q, is it of order to pay with a small amount of coins along with notes, also is asking for change from an escort offensive or acceptable??
