I heard a story about a guy who requested outcall to his house. His wife works during the day. So there they were (him and the escort)...engaged in action...and the wife unexpectedly came home. <gulp>
In my case, I once bought some Vicki's Secrets stuff for a lady and left the stuff with her. But I didn't realize the receipt had fallen on the floor (in my house). My wife found it, immediately got suspicious and began the interrogation. Luckily, her birthday was a week or two away and, thinking quickly, I said, "I bought that stuff for you. It was supposed to be a surprise." I don't know if she fully believed me or not, but the interrogation stopped. Then I had to go back to Vicki's, with the receipt, and match everything I'd bought for the escort with the same item for my wife (who's quite a few sizes larger).
The wife ended up taking it back to Vicki's and getting a refund.
