Cursing at the Toy Store

I'm a vulgarian by nature; I love the cathartic nature of using naughty words, but I work at a toy store.
Rest assured, when the final door is locked and the last child is beyond earshot, my co-workers and my language becomes saltier than the bottom of a bag of pretzels. But when we're open...
My boss says, "Sugar!" in vain, store open or closed, but in the holiday stress and opening a new store lets the occasional "Shit!" out. I'm very proud of him.

My safe curse is, "Shiz!", which magically turns to "Flaming bags of shiz!" of "Shiz-wah!" for no explainable reason.

My favorite, however, is my comrade Lizzy's with her "Fudge!" which expands to "Fudge McGirk!" when a little extra color is needed. But in times of extreme stress it becomes,"Fudge McGirk making his final Broadway appearance!"
Religion is the last refuge of a scoundrel, so please Lord make this my last Christmas working in retail. I actually want to enjoy it next time. Amen.
