Ian - sorry, don't understand the damage bit
This is a open forum for all to see, including Sam Smith's, and the authorities.
1. You stated that the quiz was not in good taste and people where walking out, you also implied it was the managers fault for not proof reading the questions.
2. That there was children in the room. That could be against the licensing laws for that pub.
3. You stated that the managers was at your side of the bar drinking. Implying they should have been working.
Geronimo, now try reading your post from the eyes of their bosses at Sam Smith's . Then maybe the penny will drop why you should have brought up your concerns with the manager in person.
Your not the first and you won't be the last one to post without thinking about the consequences their post can make to the manager concerned.
