"Unhappy with my A&E Experience"

I am disgusted with service, arrived in the early evening left in the early morning around 7 hours later for just about 5 minutes of attention, you would have thought with suspected "bead on the brain" some kind of priorities would be given.

Having called 111 (as not to burden services) I was told in so many words I must go to A&E, for the symptoms I gave I was advised I could have "a bead on the brain" this followed a recent impact to head.

I arrived at A&E (now know as A&W - arrive and wait) in the evening thinking I had beaten the weekend rush but as it happens only two people joined the line after me.  In summary I was seen in 'person' for a total of +/- 5 minutes (nurse who took my vitals, just over 2 minutes, about a minute with doctor, ct scan and then feed back from another Doctor about 30 seconds).

I politely asked a staff member (after being there for 5 hours) whom I assumed was in charge (bit confused as for some odd reason there are not on but 16 different uniforms - levels), if I could come back and or make an appointment, they just flippantly said you will be leaving against medical advise, after 6 hours humbly suggest any opportunity to improve my situation had well passed.
