If you contact the wedding boss, you don't have to talk about the price. Generally, the price of 200-300 is already a live price, and no commission is needed at all. If you contact the wedding staff, it is actually a question of refund. Depends on how much work he can give you a year. This is something you have to talk about in private, usually 5% to 10%. Of course, this is rare, because most people go to the wedding by themselves.

On the issue of fixed loss: First of all, your auto insurance must be complete. Usually the owner drives the car. If your car is a company car, you get it yourself, that is, you drive it yourself. It's not necessarily the groom who drives to pick up the bride. You need to negotiate with the wedding company. Self-driving cars are usually TT or Z4 sports cars or there is not much space in the car. Although the handling is very good, the average person rarely drives it, so you must fully insure and negotiate.
