Hitting on clients is a big no-no. Lucky for you this surgeon / client is single. If he were in a LTR or married, it'd simply take a few words from his jealous wife / GF for you to lose that fat contract. Or maybe one of his assistants might have the hots for him and hate your female staff for hitting on him, and try to sabotage your contract. Hell, maybe his colleagues' wives have seen it and may put a word or two in their husbands' ears about not using your service. Either way, discipline your staff, don't let them do this, it's not good for your bottom line.
