2 questions for delivery people: doordash, HEB, postmates, etc.

First off, fucking *thank you* for doing what you're doing!!

Question 1: for a contactless delivery, if I leave a tip in an envelope outside the door (under the mat, taped to the door, whatever), are y'all worried about germs on the envelope or money inside? Would it make it better if I included a note saying I'd doused everything in my hand sanitizer, which is why it may smell like bourbon? Would you rather the envelope be in a sandwich bag? Or does it even matter to you? I'm trying to be extra careful and want to make sure y'all stay safe too, and I'm gonna fucking tip if you're delivering stuff.

Question 2: if I were to leave a little bottle of hand sanitizer out for you, but it's in an unmarked travel bottle, would you take it if I put a note on it saying what it is? I have a very large bottle from a distillery and a s**t ton of little unused travel bottles (for some reason). I don't mind leaving a bottle out for delivery people with a label on it but would you be interested? Would that seem weird?

Again, thanks for doing what you're doing!
