When you've worked overtime all week at a bar, sometimes until 3am-4am then have to open the next morning and you are mentally and physically exhausted. You may or may not have been doing drugs in order to stay up all night and have energy for work. Then you are out of drugs and you still have to work a morning shift and deal with stupid ass customers (like AC Dave, cough.) so you just drink a lot of caffeine and manage.
Anthony was out because his baby momma had twins, so Deanna was here until 5am last night so she is rallying to open the bar this morning at 10:30am.
