Guy grabs butt on first date?

I went on a coffee date with a guy from Tinder and (my profile is I'm not into hookups at all) and we had a great conversation. As we said goodbye at my car, he leaned in for a kiss (which I wasn't expecting) and I pulled away pretty quickly. At the same time, he put his hand on my waist and then to my butt for a second. I WAS not comfortable with that at all. Is that something that is expected - cause I sure didn't expect it.
