Oh, pah-leezzee!!! I feel all of your pain.
One and I mean ONE of my DH's motorcycle friends needed a patch sewn on his leather vest and asked me very nicely to do it. Sure, no problem.
Well, a couple of other guys were around and saw this and now want me to bring my precious little FW to motorcycle rallies to sew on patches for people I don't even know. I had to tell them that the machine broke sewing the leather. I feel terrible telling a lie - - I don't do that whenever possible and besides, now I worry that one of them will see that the machine is not broken. See what happens when I lie?
