So, I left a note for the two guys at the reception of their hotel with my number and the mention of going for drinks. I received a text later that night from one of them that they had stomach issues and that he would LOVE to have drinks with me the next day. Sadly, I was leaving the next day.

I replied that morning that I was leaving and they should have a great time with the rest of their trip.

A couple hours later, my phone rings. The guy enquiring whether I was still around. I mention that I am already at the airport ready to leave. He asks me to take his email address and write to him. He tells me that they will be flying out of London at the end to go back to the US. Perhaps...
