Since BoardTrot was created, Sunny usually sells her smoothies at this new location on the weekends because many ponies enjoy themselves there after a long week of work and study.

It was now Saturday, and Sunny was selling her smoothies as usual, since she is the only employee, she has fewer days off so as not to disappoint her customers because they know that she always makes the best smoothies in Maretime Bay.

That day, Sunny came back from her lunch break to continue working until she felt the need to pee.

Sunny: (talks to herself) Darn it, why did I got urge in doing this now? But now, here's your next customer and try to hold it. Maybe I can take a pee break soon.

Unfortunately for her, many ponies of all ages started lining up to buy her smoothies. Many of them were thirsty after having fun with many toys, while some wanted to cool off because the day was so hot.

This took all day, even the same ponies that Sunny received wanted to drink smoothies over and over, making it a mental torture for her, trying not to think about fluids while making so many smoothies for them.

After a long afternoon, Posey was the last customer and Sunny was relieved to know that she could finally make her very-well deserved pee.

Sunny: (in her mind) Finally, I'm going to explode! Gotta go so bad!

When Sunny gave Posey the smoothie, she closed the store and immediately went behind it to pee (just like she does behind her smoothie truck), knowing that she could barely walk and was crossing her legs tightly.

Sunny: (talks to herself) Ugh, I know this place isn't remote, but I can't take it anymore. I'm gonna to pee right here!

She was about to pee until she saw if anypony was near her, but she found a trash can.

Sunny: (in her mind) A trash can! Perfect! [she walks over] I know somepony might see me, but that's really an emergency. There's no time to wait!

So, she started to pee and seeing how the stream was a little distant and loud after she reached her limit and almost burst, she closed her eyes to make sure she would be less embarrassed if somepony saw her and had her relief moment perfect.

In this moment, Posey was slurping her smoothie until she noticed a running fluid sound.

Posey: (in her mind) What noise is that? [she walks to the right side of the smoothie store which has a trash can] Ew, that's disgusting, but whoa, she really has a good aiming.

Posey was disgusted, but at the same time she was impressed in seeing her favorite female smoothie seller peeing standing up and having a good aiming like a stallion. But also, she was kinda embarassed and walked away from Sunny (she was still with her eyes closed).

After a long whiz, she opened her eyes and noticed her technique worked without knowing if somepony saw her and walked back to Crystal Brighthouse to make dinner for her and for hwr friends.
