dong my first live event…(covid) concerns and questions

I have read for people in person before, but never at a proper event with booths and fees and everything. ETA – this is an outside event, but i realize that doesnt neccessarily matter when I'm across the table from someone.

I'm pretty comfortable with the reading aspect but – I'm a little nervous about covid still and wondering if i should back out. I'd wear a mask of course, but not everyone else will and a barrier doesn't seem right for this situation (where would i get something like that anyway).

Also wondering if i need to have the disclaimers etc displayed or at least available?

Do people put out tip jars on top of charging or is that tacky?
