Friend came down to stay in the south of England with me for a few days. We normally alternate who goes to who. He and I tend to pay similar but split bills and have similar attitude to money. I ended up buying our takeaway the first night (£30) and a round of drinks last night (£20). We tend to transfer each other the excess after but he hasn’t brought it up and I feel really tight for asking! How do I say it? I’m fairly sure he’s not out of pocket but was going to say something like, “let me know if I owe you anything and will transfer! Think I paid for the Chinese and drinks but otherwise all square!” We both have well paying jobs, him about 10k more actually (context!)
