I was chased by some guy

with a floor sweeper today. I was in the grocery store and I noticed him going up and down the isles. I started shopping and naturally, he came up my isle. Then I went to the next isle. Same thing. So I skipped an isle and for about 2 minutes he wasn't there, so I thought I had him. Nope, there he was again. So I walked back to the isles that were already done to get away from him. I felt like a dog that barks at the vacuum cleaner.
