Best of luck 3.26.
I do hope your fears prove groundless. You say that you felt on the way there that something bad was going to happen. I wonder whether that feeling has distorted a small incident into seeming much worse. Perhaps you were unwell, or having some sort of panic attack during the evening - for instance, a high temperature can cast a nightmarish pall over things when you try to remember back. Even overtiredness can distort perceptions. I don't mean to trivialise it - those things can have an unexpectedly big effect. Even random stress can make things very strange.
If it turns out to be the case that you were set up by these people, then they surely must have very little credibility.
