Yes! A lot of sales people, call centers, waiters/waitresses, managers need it!
A new restaurants opens, my sister goes with her friends for breakfast and get mixed up orders THREE times! Not to mention the careless manager. They tell him we wont pay... he goes "be my guest". He does not even try to make it up to them
Telemarketers who cannot understand "NOT interested" and keep asking for a minute or two to at least convince me into getting their products! I mean they want me to buy new shampoo, I tell them I am bald, they still wanna talk!
Call centers! Yes, I ask about an offer, she goes the promotion period is over, I ask her what was it about, and she say why do you wanna know? ITS BECAUSE I WANNA KNOW! And its not like she ask why do you wanna know? She goes and interrupt me before I finish my question and tell me with a sarcastic tone that I am TOO late to be asking about it! What if I wanna understand the ad itself!
Its not just that! I go into the elevator and someone burps! WTH! No sorry no excuse me NO NOTHING!
