Three weeks ago I bought tickets for a show for a group of friends . All had confirmed they wanted to go. Most of them paid me back straight away Am still chasing the money from three of them. I’ve been really polite and light hearted about it. Not singled anyone out on the group chat. Polite pm to them each-just a little nudge.No response. Am self employed and it’s been a tough three years - they all know that . It’s not a fortune but it’s the principle , it’s cringey to have to keep asking . Am I over reacting?
