What's professional about it? It's making it harder for the public to purchase your product. Surely the opposite of professional. If someone is still looking at buying a car today then they don't give a monkeys about the virus and the last person they'll want to buy from is someone's who might be a bit paranoid about it... no offence intended, just my thoughts.
Therefore, business as usual. Take your precautions - no handshakes, antibac spray , wiping desks, but don't go changing the formula.
Maybe this is controversial?
