I needed to repair something and it was what I found from a Google search. Once you're there, you can easily feel unwelcome in the place. The brunette lady was awfully unfriendly and refused to help me once and skipped my turn the second time. The other lady was OK but still the whole ambiance is unfriendly and unwelcoming.
I would only go there again if it's convenient, but not because I like it.
And, yes, the customer service quality is color coded!
