What’s for sale?

Two young businessmen in Florida were sitting down for a break in their soon-to-be new store in the shopping mall.  As yet, the store wasn’t ready, with only a few shelves and display racks set up. One said to the other, “I’ll bet that any minute now some senior is going to walk by, put his face to the window, and ask what we’re selling.” Sure enough, just a moment later, a curious senior gentleman walked up to the window, looked around intensely and rapped on the glass, then in a loud voice asked, “What are you sellin’ here?” One of the men replied sarcastically, “We’re selling ass-holes.” Without skipping a beat, the old timer said, “You’re doing well, only two left.”
