I work infrequently at a local small business PC repair store called (I know it's not original) Computer City. I have a key and get called in at night to handle all the stuff their techs couldn't handle. Unofficially, I'm the "night time tech." I get all the laptop stuff they're too scared to handle too
I go in at most three nights a week, but I do order parts for people and recommend and build systems so I guess I'm influential in sales so I'm retail also.
It's a long shot, because I know it's not a chain, but does Intel happen to have a wildcard in that unlisted list of retail chains such as "small business?"
I was working daily but I got tired of being the only one dealing with customers when the owner screwed up so much and having to sacrifice all day for what I could do by staying up late at night. Also, dealing with customers meant I usually didn't even get to the tech work until after closing anyway and because that was my job I said "from now on, I'm coming in at night. Take it or leave it" They still call me in during the day if a customer needs a rush job, so I still do get some hours in the retail portion of the business.
