Do all guys lie?

So I'm in Austin, TX for work and I'm at a restaurant eating lunch by myself. There's these two people sitting at the table next to me and the guy starts talking to me about my food. We start talking about work as they seem to be consultants too. He asks about travel and I tell them that I'm travelling now and will be here for the weekend. He says that him and his friends will be hanging out on Friday and I should come along if I don't know anyone. So I give him my number so we can all hang out on Friday. He calls and leaves a message on Friday asking if I wanted to meet for dinner. What? What happened to his friends? Anyways, I call back and tell him that I'm not sure what time I'll be off of work but he says he'll wait. I relunctantly say sure...cause what else do I have to do? Finally I drive back to the hotel and it's crazy busy downtown and it takes me over half an hour to get parking. The hotel parking is packed and finally after entering the hotel parking lot three times the manager directs me to the valet parking area and gives me the code. I call that guy and tell him that I'm not in a mood to go out anymore. Guys should just really be upfront with you! Cause had I known that he wanted to go on a date, I would have never given out my number...he was totally not my type.
