Are you referring to the big box store, that's a combination building supply/hardware/appliance/etc. store? I've always had excellent service at my local one. I guess they vary by location.
That's the one. Maybe it's just the ones near me, I don't know, but I avoid them now like the plague. The last few times I was in there, you couldn't find an employee ANYWHERE. It was like they'd all gone to break at the same time.
My very last visit was a 20-minute waiting game. I had questions and looked high and low for someone, ANYONE, to ask. Finally had to go to the service desk, who paged someone from the department I was in. No response. I asked them to page again. Nothing. A third page eventually produced quite possibly the least-helpful person in existence. This fellow clearly didn't want to be there at all.
I later found out from somebody who had recently worked for them that the company is pursuing a 'absolute rock-bottom staffing' policy, requiring that some employees are covering two or even three departments ALONE. I'm told the pay stinks and the turnover rate rivals that of fast-food joints. There are other stories and so forth I've heard.
