I wouldn't use a urinal either (I never do anyway, as a former licensed plumber, thosef'n things are NASTY imo). I also flush twice with my back turned before using a public toilet.. not ideal but better than not I think.

I work in hospital

Flushing toilets leads to aerosolized water droplets from the toilet spreading around the room and contaminating nearby surfaces[1].

I know, but so does peeing into it. At least when you flush it's re-diluted.
