Went to the shop had a look around, wanted to buy a $2k gaming PC. Sat down at one of the computers to have a look at some parts to get an idea of some pricing. Then one of the elderly sales consultants came over and said in a very annoyed/frustrated tone of voice "Those computers are for sales staff only" instead of asking "is there anything I can help you with?" In polite and friendly tone.

Just wanted to let management know that's exactly how you lose a $2k + sale. Further to that... My partner bought a gaming PC from there and the exact same salesman tried to undersell her from a $2.5k PC down to a $1.3k PC up the point where he was being forceful and pushy to go for the cheaper PC - what that makes the customer feel is that they are being undermined when they know what they want...

I am in sales too and that's no way to deal with clients that are actively making an effort to come into your shop for a service and then not getting it.
