No, definitely wouldn't want to go to either of those people.
I had something similair happen recently. There is only one cable company that will service my area, and they are a small company. So I went there and when I was there I had to call my boyfriend to confirm something and a technician and receptionish where sitting there badmouthing customers calling them F'ing Idiots and the such. All I could think was "do I want to deal with that?" Um....NO! I was outta there fast. As far as I'm concerned, if a customer is present you need to be polite and professional. period.
