I'm going away on a hen trip for my cousins wedding. When we booked it I paid for the brides share up front with the agreement the hens would pay me their share back. This was 6 months ago. We are a month out and despite me asking a few times, none of the hens have paid me yet. AIBU to ask for this to be paid within the next week? I have expenses for the trip which I was planning to cover with this that I cant yet. For context its around £400
