We provide gel and also disposable gloves if needed. To be honest, the gel is antibacterial not antiviral and the virus is hardly likely to be spread via touch anyway unless someone puts something in their mouth or rubs their eyes after touching. Recently finished our first show, 4 days, and had no problem. as we are i a gazebo people waited n to kit was reasonably clear and we didn't insist on masks. Common sense is a far better antiviral than the gel stuff. Most people are wary of picking things up in caser they break them anyway even in normal times so encouraging people to pick up is (IMHO) fine. Ben doing shows for over a decade and always encouraged touching, picking up etc.
