The Smell of Fresh Boxes in the Backroom

I started my new job today at Walmart. As I said earlier, I already worked at Walmart, but I was transferred to a different department. I had fun today. It wasn't too hard or too crazy. I did a lot more physical work and I'm kind of sore, but I'm sure it will go away after a couple days. Basically, I scanned boxes to count how many items we had in stock for inventory. Then we moved some pallets filled with stuff that loved to topple over on me and then we set up pallets for the truck crew. Setting up the pallets was the main source of energy. When I was counting the items, they'd always take my gemeni (handheld machine) and do things for me on it. I wanted to know how to do it myself though so I could deal with it if I end up in that situation. I suppose I'll learn over time though. Hopefully, with this schedule, it will be more regular. As a cashier, I worked swing-shift, which means they scheduled me whenever they damn well pleased to schedule me. As a BIT Team Member, I should be working from 10pm to 7am every day. So I'm actually thinking about getting a second job. Just hire on as part-time for 4-5 hours a day. That way, I'll have a couple hours after to work to do things I like and I'll be making good money. I want to get a waitressing job so I can get tips, but without a waitressing past, I'm not sure how well that will work out.
I suppose I should just wait and see if my schedule really is going to even out or if I just have high hopes at this point. They're training me on days so I'll be all sorts of prepared for nights, even though they say nights are more relaxed. Maybe I should just bag all of my jobs and get hired on at a mine for $20+ an hour? But who's to say that I'll like my job out there? That's the risk. I know I'll love being a waitress. Even though you get dicks every now and then, how more different can it be than cashiering via dealing with the customers? Maybe I don't know what I'm talking about. I can at least try it out, right?
If all else fails, I can just rely on Steve to support me, right?
