Guy asked if we served alcohol

I was working drive thru and he asked about the differences between the cold brew and nitro cold brew. Then he asked if he could have some alcohol in it. I had to ask him to clarify multiple times because I was in disbelief I thought he might have meant to say cold foam or something 😭😭😭 but no. I just told him we can’t do that and we don’t serve alcoholic beverages and he was like oh 😕
