>John: "Sorry if that round
of tequila shots
I ordered at the end of the night pushed
you over the edge."
: "Haha, no biggie. Cost of doing business with you man."
In this case, "doing business" refers to hanging
out with John. the "cost" is the risk of getting too drunk because
John likes to order tequila shots
is saying that by voluntarily hanging
out with John last night, he implicitly accepted the risk of having a tequila
shot served to him that may not have been a good idea but that he, in his intoxicated state, may consume anyways.
