What do you say if someone farts in a public toilet?

It can be awkward when someone farts in a public toilet. Here are a few things you can say to respond to this situation:

- "Excuse me, but I think you left the door open."

- "I'm not sure if you noticed, but there's a strong smell in here."

- "Could you please be mindful of others and try to be a little more discreet?"

- "I'm sorry, but I'm having a hard time concentrating with all the noise."

Try to be polite and respectful when addressing this issue, and avoid making any comments that could be considered rude or offensive.
