Five of us had dinner last night - two couples and myself (I’m a single parent). At the end when the bill arrived, one of the couples declared that the bill would be split three ways. I’m not sure how it made sense that a bill for a party of five was split three ways but was too embarrassed to say anything. As a result I’m £20 out of pocket. AIBU to think that the bill should not
have been split three ways? Also, should I just stay quiet about the £20 and never go out with them again? What is the correct bill-splitting etiquette in this situation?
