I have had somewhat similar experiences at times, but not as bad as yours I think. My worst one was this woman who kept claiming to almost have arrived as I stood outside in below-freezing temperatures for over 20 minutes to give her free stuff.

Finally left the item on the sidewalk and went inside. 40 minutes later she sent a text thanking me for it. I don’t understand why she lied over and over about her location. So stupid and inconsiderate.
