As a catering waiter, if the business of this store is average, it may be easier, and there is no possibility of working at night, but your salary will not be very high.
If the business in the place where you work is particularly hot, it must be very hard for you to work as a waiter and you need to work overtime frequently. Being a waiter is not only tiring at night, but also during the day shift, because there are many people during the day, and the more people to serve, the greater the workload.
