This really depends on your beliefs in if gender discrimination is as big of a deal as racial discrimination. The 14th amendment is the Equal Protection Clause, it was mainly for the slaves that had been freed in the U.S after the civil war. It basically forbids the states to restrict basic rights of citizens without going through the process of law or being protected by the law. But has recently been used in cases to of gender discrimination.
I believe it is perfectly justified for the 14th amendment to be acted in cases of gender discrimination. The 14th amendment does not have to be dedicated completely to race, but can have multiple purposes and be dedicated to gender discrimination as well. Because the 14th amendment does not mention race in its context, but mentions that basic rights shall not be stripped from citizens.
The best way to handle this situation is to tell to the guest who is in a hurry that you won't be able to take his request as the top priority because there are others who are first in line before him. It would be best to advice him that his order would still be taken care of and would do it as fast as it can with trying to explain that he's not the only one in the restaurant to assure him and prevent conflict.
