What does "Make that [someone]" mean? Does it mean to please or satisfy someone? If so, could you please tell me some examples as well?

"Make that" means to adjust the original statement. In this context, first, only one person came to buy something, then soon afterward more people came. It changed from one "customer" to many "customers". The phrase usually comes with an increase in the number of something. Ex: I'd like to order a hot chocolate... Make that two hot chocolates! Thanks. Ex: Oh look, one person has arrived at the party. Oh! Make that three people.
