Please be considerate.
If you need assistance on how to use a toilet please ask someone.
You urinate in the bowl, not on the seat and the liners, these are the paper sheets in the utensil hanging on the wall, can be used to line the seat. This is for your protection, although I feel it is the rest of us who needs protection from you. You are not at home now you are using a public facility that is for everyone on this floor.
