I'm currently staying in a 5* Marriott in Pune. I usually brush my teeth with bottled water. This morning I got distracted and started using tap water instead. I think I only rinsed the brush under tap water and started brushing for a few seconds.
As soon as I realised this, I rinsed my mouth and the brush with bottled water.
I'm now worried I'll be getting sick on the last day of my trip!
