We have 4 Tmobile lines. All 4 lines have current iPhone 6s Plus' and Samsung, so it's not like we don't spend a lot there. Pay Jump plans - buy "several" new phones a year - member for over 10 yrs. We buy plenty of accessories as well. Thousands of dollars spent on phones and accessories. So we come into this location because we are in the neighborhood (not our regular Mesa tmobile store) and ask them to put on a screen protector (because they have the skills). The guy refused to put it on because we didn't buy at Tmobile and they couldn't be responsible. Screw that! For literally years my Tmobile in Mesa has put my (non-tmobile) screen protector on a $600-$700 phone without being righteous acting. The store was literally dead, not one person in there but like 5 employees standing around, not like we were interrupting anything! When we headed home we stopped at our Tmobile in Mesa and without fail they gave us no guff. When customers spend thousands a year and you can't put on a screen protector for them unless they pay the high bucks for a Tmobile one. Literally everything else is bought there. I have never felt such snobbiness/laziness at any other Tmobile. They could say, we can do it but we can't take responsibility. Everyone knows it's a skill that is learned with repetitiveness which many phone owners don't have. If Tmobile in general refused to put on a non Tmobile screen protector I (all 4 lines) would quit buying any accessories from them PERIOD! A little bit of customer service goes a long way. Bah Humbug to you Snobs at this location.
