That was my exact thought!
Interesting how things have changed in a decade and with the entire bank crisis and downturn in the US. TS salesmen haven't changed much, but the offerings have; although I disagree with FL having the worst. I think they've been to best of all my experiences; but in FL that's been limited to Starwood.
Most of these tips were pretty radical. If I agree to 90 minutes, and I have done my time and am no longer enjoying it, I get up and leave "thank you our time is now up". It's not like they can hold you hostage (in the US). Sometimes I stay longer if I am interested in what they are saying, or am enjoying the conversation, but most of the time that's just wasting the salesman's time.
