I was making a pecan cluster blizzard today, and the guy came back 5 minutes after I gave it to him and said there were no pecans in it. I told him that candied pecans, when hit by a metal mixing spindle at max settings, basically shatter into tiny bits. He still did not understand. I told him I would give him pecans for no extra charge, and he started to get smart with me. Long story short, he yelled at me for a few minutes while I just smiled and told him to have a nice day. I was waiting for him to chuck the blizzard at me, at which point I would have called the cops on his old ass. It's too bad we were busy, my manager really wanted to deal with that (have his fun) but we were short-handed and in a big rush.
