"Signs on buses reinforcing correct procedures "

I am aware of the concern re misuse of A&E and the steps being take to combat this. While in Portsmouth earlier this year I noticed that most of the single deck buses had an advertisement on the side. This covered the whole of the length of the bus below window level. The ad. was divided into four columns, headed Pharmacy/Chemist, GP, Walk In Centre and A&E. Under each was a list of typical complaints which could appropriately be dealt with by the different services. I thought this was a good idea as it reinforced the correct procedures to follow and also educated those who may not be familiar with our way of doing things (ie immigrants, foreign students etc.). Just a thought.
