My two contributions:
Today I heard about a “Call Navigator” who would answer my call shortly when on hold for an hour. How about you staff your place to answer my fucking phone call? I just want an answer from a human. I don’t want to be directed or navigated.
Hotels and restaurants referring to customers as “guests.” Nope. I have guests in my house. They pay for nothing. They are there by permission and invitation. These places are referring to “customers” which all businesses have and there is nothing wrong with that word. But don’t tell me I’m a guest and then give me a bill.
