On this, we totally agree, Brother!
I'd just love to know how the conversation between the Manager and the two guys went...
Did she ask them to leave after a "reasonable" amount of time, when it became obvious that they were not going to purchase anything? - Was she rude, threatening and nasty?
Did they respond in a rude, threatening and nasty manner at her request to either purchase something or leave? - Or did they repeatedly explain that they were waiting for another person to arrive, before placing an order, and determined to stand their ground?
Inquiring minds wanna know...
