As a part timer I don't get much free stuff handed to me but I do still get a crap load of free stuff. Mainly because I know of the right asses to kiss
lol...
I would suggest if you want a t shirt to start chumming up with the lady or dude who handles that stuff first hand. Given, that I did have a little romantic fling with the lady who hands out the free **** and that is probably why I have a leather UPS jacket but still anybody could do it just make friends.
The cookout thing I definitely feel where you are coming from. We get BBQ's every other month and we get a huge one next Friday for going a year without an injury and the drivers are more or less left out.
Now with that said...
The amount of money you guys make is literally 6-10X what we make. You could literally fund our entire BBQ with one paycheck and still have more than we make in a week. That is the real reason. The company spends so much on the driver pay that they don't have a lot left over to feed you guys and give you free **** as well. They pay us so little for how hard we work that a couple burgers or some try tip on a friday is the least they can do.
Put it this way. I will trade my closet full of ups shirts, beanies, hats, jackets, backpacks, waterbottles, and the four years of free meals every other month for your weekly income.
Brush it off, be glad you aren't wearing your fingers raw in the hub, and take your fat ass paycheck and go buy yourself a steak.
