I wasn't hiding, promise

Last night, I stopped in at Home Fabrics to look for some outdoor upholstery fabric. I need to make many cushions for my patio furniture, and I'm feeling like I can handle that right now, so I measured, calculated, and figured out I need about 6 yards for the cushions for one furniture group, which means I need it to be cheap. Hence my stop at Home Fabrics.
I'm in the back, wandering among the sale stuff, finding all kinds of possibilities. At some point, they turn the music off, and I wonder, did they not like that song, or what?
About 1/2 hour later, one of the employees walks past me, stops dead, and calls out to the other, "Hey, remember that story I was just telling you? Here's another one!", then turns to me and says, "Can I help you find something?" I reply that I'm just browsing, looking for that just-right something. Then she says, "We're actually closed. But if you have something you need cut, he can help you up front."
Oops.
I guess that's why they turned off the music.
I bought 4 yards of something I thought might work for one of the other pieces. I was too embarrassed to try to figure out what else I wanted.
What kind of fabric store closes at 6pm 6:30pm?
