First: English isn’t my native language so I am sorry in advance for any spelling and/or grammar mistakes.
Second: I never wrote anything like this before and it is the first time I am writing down this memory so go easy on me.
Five years ago, I (M) visited a close friend of mine for a weekend trip in another city. Shortly before I arrived there, he texted me that he was really sorry but something came up at work and he would probably need another hour before he could pick me up from the train station. It was a lovely morning in June and I felt like having all the time in the world so I texted him back that he shouldn’t worry, I would get myself some coffee and jokingly told him that he was going to pay for the drinks that night.
When my train entered the station I first and foremost needed to pee. It was already kind of urgent. So I hurried inside the building and found a nice coffee shop on one of the upper levels. I went to the bathroom which was outside the shop but unfortunately the door was closed and a sign told me it was for paying costumers only and the stuff hands out the keys when needed.
