They run concessions at sports arenas. I didn't understand why (a) the contract at YNP with Delaware North was not renewed, and (b) why it was given to Aramark, of all companies. Aramark has shown repeatedly that it doesn't give a crap about people visiting Yosemite, doing anything it can to cut costs (and thus services). TM-area free shuttle? Nope, not even for a fee. Skiing at BP? Cancelled two years ago, and last year closed *early* b/c of record snow, whereas at Squaw Valley and Mammoth in CA and at resorts in CO, skiing stayed open until JUNE! Convert GP store into a winter hostel? Nope. Sufficient number of shuttle buses to accommodate visitors to the valley? Nope. Fire employees in 2020 when the park is closed because of the Wuhan virus panic? Sure. Close Vogelsang and Merced HSCs, under the ruse of "protecting the environment"? Sure. Plenty of other examples.
The worst part is that they have squandered any institutional memory that might have been there. Treat your employees like crap, even (or especially) if they're seasonal, and you won't have employees. Even if DNR is brought back when the contract with Aramark expires (in 2030? 2031?), it will take years to rebuild the goodwill that the concession operator had with employees.
