The assertion that a team may be 'Palace in disguise' is somewhat odd if Palace happen to be playing that day.
However, it could be Palace's second string which would give credence to the original suggestion.
I still have found no evidence to suggest a Sussex ambulance is a mode of regular transport to go home from the AMEX. Even less that it is included in the levy we all pay. It would save me catching the 23 in the general direction of the hospital.
