Obviously this is a lighthearted AIBU! Having another couple for dinner Saturday night. One of whom is what he terms a “very plain eater”. As a result am making steak/veggies/pepper sauce for main course. Would I be unreasonable to serve M&S mash rather than peeling/ boiling/mashing my own? Partner won’t be home from work until half hour before the guests are due so can’t be of help. I accept it’s lazy but would it look like I’ve served a bad substitute rather than the homemade stuff which has the potential not to be great?!
