Depends how you define "bad/incompetent" as I think they're all bad...
It's like airlines, they're all bad. Banks, they're all bad. The problem is that we don't have alternatives.
I recently met a saleswoman who knew very little, and in fact she knew some things that were incorrect. She wasn't very good. But she wasn't offensive, just tragically uninformed, confused, and not very bright...
1. She couldn't tell the difference between a mainspring and a hairspring.
2. "This one has a
micro rotor which is supposed to be very good" and she has no idea what the pros/cons of micro-rotors are. I did ask her what the benefits of the micro-rotor was, and she her response was not only unconvincing, but showed she knew even less about physics than I thought when she said that micro rotors were more efficient than large rotors. She also claimed she went to the brand's ambassador training program and showed me photos and pointed out her lapel pin.
3. She was very superficial, "that watch looks great on you, you should buy it!" I gently corrected her and reminded her that it was I who looked great, not the watch. She did like my joke.
4. She was very polite throughout the whole process. But she used the wrong type of pen on the warranty paperwork when I specifically told her to use a specific pen (I think everyone should take some basic calligraphy course to fill out warranty paperwork). At least she didn't mis-spell anything.
I realize I have high standards... But a salesperson who sells $40,000 watches should be elegant individuals through and through. Unfortunately... I can see that it's difficult to hire someone to sell these products who would meet my requirements.
Well... I bought it anyways, evidently with the warranty paperwork. I know I shouldn't support bad jewelers nor bad employees, but that's just par for the course these days. If I upheld my high standards, I wouldn't be able to buy anything!
