NOT A FAN OF THE NIGHT SHIFT

Last night at work this guy came in to buy a few things. I rang through all his stuff and then he kinda whispered that he wanted something else too. He had a really raspy voice so I didn't quite catch what he said, so he repeated it. I didn't think I heard him right because I had no idea what he was talking about. So I asked him again.
"A pack of New York Rubbers" he said. I just kinda looked at him very confused. I was totally clueless. So he told me what they actually were, I'll let you guess, and I could feel my face turn bright red.
"Uh, mmm, uh... right over here." I choked out. They were behind the customer service desk, so I had to let him back there. He picked some up and then paid for them. Then he called down one of the aisles, "Com'on Smiley", and a girl in rather interesting attire followed him out.

A little later that night, another gentleman came in looking for the same product. So I took him behind the customer service desk, hoping he would just pick up a pack so I could get this over with. But no. He has the boldness to ask what kind I thought were the best, and what sizes they come in. As if I know. He spent like ten minutes looking at all the different kinds. I was very uncomfortable.
I can't wait till my next night shift.
