How do you guys handle girls leaving mid session to answer a guy hammering the door bell?

I was enjoying a massage today, a very good one warm oil, great music, beautiful girl going over some very tired muscles really well, I was just totally zoned out, then I hear the door bell, no biggie just ignore it, well the guy rings it 3 times in a row back to back, the girl excuses herself to go deal with the annoyance.

The guy comes into reception I can hear her clearly say to the guy, im busy now would you like to come back in 30mins?

he responds, oh yes I would love to spend 30 minutes with you.

She goes no come back in 30minutes

He says yes we will have a great time together.

The girl was super clear I have no clue what he was thinking, she eventually painfully got him to leave, but when she came back she didn't resume the massage she started toweling me off, I lost my peaceful state of mind and the last portion of my massage, felt abit ripped off she didn't do my lower left side.

Whatever we move onto better things straight away, then not even 10minutes later as we are in the middle of things, the door bell starts going again over and over and over, she excuses herself goes out, I can hear THE SAME GUY at the door asking is she ready now.

I didn't show it as I like seeing her don't want things to be awkward over it, but I felt pretty pissed off in the moment by the whole situation.
