Ive done a few.
When I was about 17 I spent the summer working a t a Canal Boat tour operators. My job was to ride along on the boat, serve tea and biscuits and open the locks along the way. After the boat returns clean up. Very chilled out and easy money.
Was in the military so Ive visited various bases and training areas around the UK. Did an operational tour in Afghanistan for 6 months.
After the military ive done a few random jobs.
Worked at a summer camp in the USA for inner-city boys, which was fun but some of the kids were a handful. Plenty of swearing, fighting and boys being boys.
Also did a Summer Camp in Hong Kong. Very different, practically lived on a beautiful beach for a couple months.
Nightshift receptionist at a hostel in Laos. Got the job by pure luck. The manager was awesome and got to meet plenty of cool people, as well as a few oddballs.
Currently in China as a EFL teacher.
