Totally offended
I had a pizza and 2 glasses of wine at the bar after staying at this hotel for 3 nights for the Mystery Shopping Providers Association conference (which is a group I co-founded in 1997. The Food and Beverage Manger, Mr. David Putnicki made a "judgement call" an decided after one wine and one pizza that they would not serve me any more food or beverage. Also they refused to serve any of my friends who were standing around me - including three people who do not drink alcohol. I do not believe I was misbehaving in any way - but Mr Putnicki, who said he had been through training to spot "people like me" said he would treat everyone who visited his bar in the same way. Yet somehow, i noticed several people around me ordering more than one beverage who were fairly out of control. Yet, the bar tenders seemed more than happy to continue serving them. 
I will go out of my way to avoid staying in Westin Hotels as a result of this visit. Incredibly rude and crude treatment of a guest who not only brought more than 150 people to their hotel, but also someone who is trained to evaluate guest services at hotels.'
I have videos of this encounter posted on youtube and am writing on my customer service blog exactly how Westin chooses to treat their customers.
