the soda mix up drama

ok so here's this whole saga i've been dealing with all week at work. my regular customer jane comes in every single day for her usual iced caramel americano and a cherry coke from the fridge. now, i love jane but she's got these like really specific requests that can get on your nerves sometimes. last week we ran out of real soda so she was like all grumpy until i found some generic brand one, and she said it tasted fine...but today i honestly thought she'd be happy with the same since i don't think she notices the difference anyways. so there's this other customer tom, who orders diet coke all the time but has a weird thing against our flavored waters. he gets really loud and stuffy if we can't get him his regular diet coke. today though, i made a mistake. i was so busy serving people that i grabbed jane's cherry coke thinking it was her usual americano (i know right?) and poured the ice from tom's cup into hers instead of giving him the actual drink. when she took a sip of her coffee she said something about how it tasted funny, but then just left without saying anything. meanwhile tom is yelling at me in line while i try to apologize and explain my mistake. after he storms out, i felt like hiding under the counter. so y'all...how do you think i should handle this with jane tomorrow? she's super chill usually so maybe it won't be a big deal but what if she noticed and is mad at me now? help! 😅
