That's right!
But you also said bris, to which I responded that there are other alternatives.
What about making the Bris early because of Zrizim Makdimim?
AFAIK, the only time you do the bris later is if there will be more people. As people tend to need to go to work, I wish to do it before 9.
Either way, I asked about how caterers code on credit cards, and you're lecturing about halacha. G-d bless ddf.
