We have recently had a huge uptick in sales. I chaulked this up to my superior marketing campaign and my bar savvy!

But upon closer inspection I noticed the bar has been packed with people wearing red to different degrees. My bartenders have also mentioned talk of people spending a bit more time in the bathroom than usual. After watching the security cameras for a bit. Yep they are mostly gang members.

I want to ask them not to come anymore. But you can't just tell people for no reason they cannot be in your bar.

Any ideas how to move them along. Without reprisals?
