Tom,
  Please calm down a bit. I checked all of the posts here, and I don’t think anyone posted an attack on you personally. what I read are offers of advice and opinions, which you asked for in you original post.
Lighten up my friend, and keep your wrath for the original offender.
BTW, I am not sure we have enough info here to connect the waitress/doper incident to the irate woman customer?? Is there another chapter to this story that might fill in the blanks?
AL
