When you go to a restaurant with friends/family , (family is extended like siblings,cousins etc ,not with spouse and kids) Do you 1) Share the bill amount equally? 2) Do you only pay for what you eat ? 3) if others take alcohol and non vegetarian food and you are a non alcoholic person and take only veg food, do you share the bill equally in this case too or insist on paying for what you ate? Just trying to understand what IL friends do. Didn't have a very pleasant experience recently. What I do is : Whether I take alcohol or not I'm ready to share the bill amount equally and always insist on the same unless the person who takes alcohol insists specifically that he will pay for his drink. If you choose to not pay do you intimate the group before? Or wait until someone in the group sends you your share of the bill and you tell "since I didn't take alcohol or non vegetarian food, I'm not paying for it ".
