Crying over split soda

Four months into my serving career at Bloggiano's, I had my first incident where a guest made me cry.
Damn it.
I blame the long weekend. I was burnt out, and made a stupid mistake.

It wasn't a very busy Tuesday morning shift, but I had a few tables. Then I got sat a party of 7 guests.
Right off the bat, things went sour when one of the women at the table reached for bread, and knocked over her diet coke all over the table.

The bussers quickly got everything cleaned up. When I went back to the table to check on things, one woman commented on why I hadn't brought refills. Ugh. Sorry.
It takes me five minutes to ring in their order, thanks to them all ordering soup and salad combos, adding and subtracting a variety of items from each . Ugh.
All goes well, and I'm informed by the hostess while they're eating that there are two birthdays at the table. Double Ugh. I'm so busy now.

I go to get the birthday cookies. We don't have any birthday plates pre-made. I KNOW I need to wow them more, so I make the pantry staff write in chocolate for this table. While I'm waiting for the plates, my busser comes in and says they're asking for the check. UGH. I give it to him, and I wait two more seconds, then follow with the birthday plates. The group smiles, and they wish the two ladies a happy birthday. I think I'm safe, but I'm not. They hand me cash and ask for the remainder of the bill to be rung on the credit card. I quickly get it done and return in a minute. They look, and say I must've miscounted the cash. My heart skips. I look in my bank. FUCK, I did. 

Now I need a manager to void the charge and re-ring in the correct amount. This is a HUGE pain in the ass, and it's happened to me once before. My manager is pissed. I show the woman proof of the void and the new charge, and she flips out. "Am I going to get TWO charges on my bank statement now??" UGHHH
I get the manager because I tell her I don't want to give incorrect information. I immediately start crying as the woman yells at the manager and I like we are five years old. 

You'd think I charged her a huge amount right?? The first charge was $40. The second, $20.
In the end, the manager voided her credit card completely, taking her amount off the bill. And I will surely get written up. I cried in the back for about 5 minutes because once I start, I can't stop.

So happy I'm not working today!
