This made me recall a sales interaction with a company myself. Somehow a sales person from a company noticed we were in the market for an somewhat expensive product their company was selling.

They always called during lunch hours (three times). When I finally had a short moment, there was (1) nothing substantial the sales person could tell me about their products or their prices, (2) they had no idea how we (public sector) have to buy things and wanted me to make an exception and when I asked them to just email me their offer to my publicly available email address (3) they didn't.

By that point that company would have been better off not having a sales person. And that type of experience was up to today nearly the only thing that happened with sales, except for one time where the company sent a technician to have a look at our circumstances which worked great.
