you are in the chechout lane with one item and cash and the person in front of you has three orders, a cart full, wants to chat, get price checks. .........
you get the idea. I always let small orders go ahead if I know I'm going to take a few minutes. But maybe it's because I have worked in retail for umpteenbillion years
when i go to France and ask a french person if they speak English and they say: "no"
and then i go: "Not even a little bit?"
and they go: "No, sorry."
and i go: "Are you sure?"
and they go: "yes"....
