Does anyone else have an issue with riders bringing their drinks with them? I have had several bring their solo cups, Styrofoam cups and whatnot with them when I pick them up. I am not sure if I should say something, like, I don't mind if you have it, but please take it with you when you leave. Heck, I would even like someone to ask me if it is okay that they have it with them. At least give me the chance to say no before you bring it. Also, I have checked several times and noticed these turds leave their crap behind.. UGH!!
