I think they did offer spare clothes but Lewis declined the offer can't say I blame him really.Been thinking about this. Undoubtedly Lewis turned up looking like some rap star, being unaware of a dress code. I simply don't believe he would deliberately try and chance his luck, as he 'is a very nice boy', if young and a bit of a muppet.
However, you would think the all England Club would be able to offer the royal box guests a shirt and tie should they turn up without one.
Snobbish enough to turn away a guest but not classy enough to assist. Going the extra mile is surely a prerequisite of the tradition pomp and ceremony of the oldest tennis tournament in the world. Shame on them.
