Carry while working as a restaurant server?

So, as the title suggest, I am looking for suggestions on how to carry while working. I currently work in a shit part of downtown doing graveyards. So I arrive around 9-10 pm and leave around 5am. I currently carry a Glock 19 IWB at about 1-2 oclock. I feel like it prints more than I'd like. I don;t like the idea of storing my weapon while working, as my current workplace attracts a lot transient people. Any suggestions would be appreciated! As to carry options and models.​tl:dr serve food late at night, and would like to not die or get robbed via /r/CCW http://bit.ly/2P36yNo
