In a cafe this morning, I ordered a sandwich and a coffee and the girl behind the counter said 'is that all?'
I said 'yes, thank you,' and she said the cost. When I then said 'could I have a bag please' she looked remarkably pissed off.
DP agrees that she looked cross but says IABU and should have asked for a bag earlier, as part of the 'is that all' question.
I disagree and say that 'is that all' refers to the food, not the container
