Rude manager and waitresses

<p>Got to this restaurant to order takeaway coffee at 1145am and met a waitress to assist.She asked regular or large then l said to her it's take away and she rudely said l know,regular or large and l pointed out to her it would help if l saw the sizes of the cups.She then ran around for a few minutes and the manager came to ask if we were fine and l told him we were waiting for coffees and he should go and check.This was now at 1155am and he said we should just wait as we had just came in  and l pointed out that coffee shouldn't take that long and he said you can't tell us what to do in our business.I think this is extremely rude.</p>
