Covid friendly ice cream bar?

I would see if the caterers would add the toppings as well if not provide gloves for the guest to use.

They actually sell individual toppings you can buy like how they have individual ketchup packets.

here is chocolate sauce packets: https://www.walmart.com/ip/Toppings-for-Ice-Cream-and-Desserts-Single-Serve-Packets/352762286?wmlspartner=wlpa&selectedSellerId=101001191

or if you've seen like little servings of caramel dips and things like that, it would work too. or even fruit preserves would work as a sauce for ice cream.

other toppings you could do would be like fun sized packets of M&Ms or something like that.

stuff like that people can just grab and go.
