After getting a tanker truck washed at a truck wash, is it standard procedure to walk around the truck to make sure the valve is closed, etc.?

If you are driving a tanker truck and you stop at a truck wash to get it washed:

#1. Do you stay in the truck while it is getting washed?

#2. Do you walk around the truck to make sure the valve cover is placed back on the tanker and that everything is ready to go before driving off?
