April Can't Come Fast Enough

I swear, working as an instore sucks so bad. I am seriously pissed right now. I cut pizzas when they come out of the oven, which is easy when things go right which they only do when I'm making the pizzas AND cutting them. Last few nights have been terrible. Last Friday night was really busy so we are supposed to have one person cutting and one person putting orders together. There is only one other crew member who knows what he's doing, because I trained him. The MOD decides to assign him another position and puts himself in that spot, and disappears for most of the night, except to walk by and jump my ass for not being fast enough. He's faster than me, I admit, because he's done this for nine years. But I'm one of two people who can handle any kind of business in that spot, and the other is a delivery driver. I realize this is petty, and I'll probably forget about it tomorrow, but this is turning into a weekly Friday ritual. The harder I try to get ahead and stay ahead the harder my managers try to keep me behind, the girls on the makeline screw up pizzas that much more often(believe me, when I tell them I need a remake, they get pissed), and I always end up staying later to catch up before I go home. I must reiterate, I love delivering, but everything else in the pizza business sucks.
