The fact that it costs more to hire a forklift driver than whatever you call the teenager that takes your money and pours your drink.
Unless employers are just more generous with forklift operators, but I doubt it.
Why does it cost more?
A forklift driver is usually hired through an agency. Companies don't hire them directly much anymore because they don't always need the extra labor.
So you the agency calls, sends you to a warehouse/distribution center, and you get on the lifts and load/unload rackings or trailers within 30 minutes of arriving on site, after the supervisor gives you the lowdown on what they want done
A starbucks employee has to be trained on how to clean the place, work the Point of Sale cash register, approach customers, handle receipts, balance the cash register, do inventory, open/close the store
that sounds like a lot more work to me, dude
