That sucks OP, online dating can be quite mysterious at times.

Why didn't you get up and leave? You don't have to be polite to rude people.

"Let me tell you a little about the Glock model 19." *audible click under the table*

unless he's selling a pyramid, you're good to go.

how did your date react?

Rage quit! (The date...)

Yeah, that happened to me once with a former coworker who I thought wanted to meet up for job search advice. I only humored her because she was an exceptional employee when we worked together (I was her manager for a while), but I couldn't believe that someone that sharp had gotten sucked into such unmitigated advantage-taking bullshit.

Step 1 : Show up. Step 2 : ???. Step 3 : Profit.

I probably would have said no to the date when I saw that the friend tagged along, and scheduled it for another time. From what I've seen, a friend accompanying on a date rarely turns out well. It's a date, a third person is unnecessary, and if you're just getting to know each other, dates can be awkward enough without a third person there. A third person just makes it more uncomfortable because it disrupts the balance, it's no longer 1 on 1. You're getting to know each other, that comes first, meeting friends can be scheduled for later, when it isn't a date.

I know a guy this happened to. He thought he was having a good date, then she started giving him the bootleg amway speech. He stayed for the whole thing, I still have no idea why. The best part was he bought her coffee so he basically paid for the sales pitch.
