I'd maybe try contacting him again if you only texted once--text might not have gone through, or he may have missed it, if lots of clients text him. Also, did you identify yourself in the text? T's often don't keep their clients' actual names in their phones. (Though ideally he should have texted back and asked who you were.)

I think it's common for T's to drink liquids during session, like soda, coffee, or water. I see why the candy thing would be annoying, and that's something you could always bring up with him if you end up seeing him again.
