When I worked fast food, we had a regular customer. A picky, fatass customer who especially pinched my last nerves. One night, she came by the drive-thru & ordered her meal, so did - done - peachy. 30 minutes later, she came back with a complaint about cold fries because she had to eat her sundae first due to melting so fast [it was summer & our humidity is torturous]. That it was our fault for not having proper temperature settings which is why the sundae melted faster than it should.
So as usual, we don't argue with customers & do whatever we can. I took her fries, put them back in the fryer & made her wait 5 minutes as if making fresh fries for her. Put them in a sack & handed it out, asked her if they were to her sanctification & she approved. Then said to me, "I should get a sundae replacement for having it eat it before my meal." I said, "That is not a reason to get a replacement, ma'am. Have a good night."
