Our SB/FA don't.
Despite cross-training (or "cross-pollinating" as my SBTL says), we're dealing with ever-shrinking hrs. Sure, everyone has that problem but we have to streatch coverage for a small, but specialized area.
Ours isn't exactly an area where you can drop someone in from another dept & expect them to prep pizzas or whip up lattes.
That's also outside the usual fun tasks we deal with that can't be done by outsiders.
Making up a dozen salads to fill the case? No prob!
Unless you're the only one on duty for the day & you're in the midst of a lunch rush. Then the ETL comes up & reminds you to add sandwiches & drinks to the case 'cause you're running low.
Like those cookies? So did everyone else so now you're pulling cookie dough to bake up while guests are yammering that they've been "standing there for 15 minutes!"
You're trying to restock your syrups, milk & cups after a morning rush but you can't even walk away from the counter because of a steady stream of guests demanding their lattes, frapps, etc. Before it even slows down, your order is being pushed from the back "to give you something to do".
My TLs are in the mix alongside us & have to listen to constant reminders to do their vibe walks & other paperwork so, no, they DON'T have it made.
