I GOT A JOB ! BUUUUTTTT......

Bella
So I'm 20 & I   recently got my very first job at this medical Marijuana dispensary yaaay me I love weed. HOWEVER.. there's a slight problem . They're only paying me $11 an hour to do three jobs. I worked 45 hours last week n I'm freakin exhausted. They have me being a receptionist, a budtender in the back AND doing drop off deliveries. On top of that I'm using my car for deliveries and putting a whole bunch of miles on my shit (they pay me gas I drove ) but still they don't help me if my car breaks down or anything . Anyways the problem is I feel like I'm still being paid too little  for my work and it's only been a week since I started the job so I can't go demanding higher pay. But what should I do in this situation ?
