Picture this: You’re in France and you want to invite a platonic French friend out to dinner at a restaurant. So you invite him or her — they seem delighted — mention a restaurant and time to meet, and then you both go on to have a wonderful meal. When you ask for the check, your friend doesn’t move or say anything about paying the bill or splitting it, and it just sits there on the table. Finally, you pick up the bill and leave feeling a little confused because you assumed you’d split the bill. After all it was just your idea to eat out and you guys are just friends — you didn’t volunteer to cover the cost!
But a-ha! You did!
