Yes, considering the food is already IN FRONT OF YOU, it is too late to change your mind.
You know that the waiter is going to be coming to the table to take your order, so plan accordingly.
You’re not the president.
I’m sure the call can wait.
In general, you probably shouldn’t interrupt anyone with your demands when they’re trying to start conversation — server or not.
There’s always the chance that it was written down wrong — crap happens — but unless you want a resentful server handling your plate of food, approach it like an adult.
You get more flies with honey.
Think about it a minute — would you do that at home?
Probably not, but if you do eat with crappy diapers on your table, maybe stay home for your meal.
