I've actually never played tabletop RPG in a 'physical format' at a table with fellow adventurers. Instead, most of my sessions were facilitated through MapTools or Roll20.
I was part of a campaign that met on a weekly basis, but for a period of time I was just moving into a new place so I had to wait to set up a new internet plan. What made matters worse was I didn't even have a vehicle available on that particular day, so in order to partake in the session that day, I had to walk my butt 30 minutes down to the nearest coffee shop to take advantage of their free wifi.
Not exactly the most bizzare, but the memories of sitting in a crowded coffee shop with headphones on and speaking with my best impression of a nasally halfling still brings a chuckle to me.
