Closest to this I’ve worked was a convenience store which included a deli.

In that context the way I would have seen it was that he probably would have come in and bought them anyways, so the only difference to me would be sticking them in three bags vs one. No different than anyone else asking to cut their pizza a different way or whatever other minor out of the ordinary changes customers wanted.

If we were swamped with orders then yeah I wouldn’t be happy about it, but you get over it and move on that is part of working retail.
