The folks who run such "travel offer" operations evoke a few issues: contempt for the people they call, anger management, and low tolerance for frustration. I'm not sure why they're involved in this miserable business, but they talk so fast and in such an unpleasant manner that it seems the customers they close are the ones they bully over the phone. Raise any objection? Politely ask to be removed? Then the entitlement begins. They demand to know why, as if it matters. They raise their voices like lunatics. They shrilly exclaim that you are irrational for not taking the offer. And when you ask them to remove your number because they're being rude, they accuse you of lying about being uninterested. Then, when you in an apparent final attempt to harass you into accepting, they interrupt you and demand, "explain! explain now what's wrong with my offer!" Finally, all I can say is "I am terminating this conversation" and hang up.
