Remember thought it is roughly £10LE (Egyptian pounds) to one of our pound coins, so therefore one of their pound coins (LE) is only worth 10p. If tipping in their own coins you will need a lot to make a pound of our money. Believe me you will not want to carry a load of Egyptian coins around with you, they way heavy and anyone will find it difficult to change them back to English currency, in fact they do not think they will.
Just remember to ask when you get your currency to get low notes, they are mucky but wash with gel.
We gave the porter/baggage lads £20 LE - for 2 suitcases = £2 sterling.
Didnt need to tip at airport.
Restaurant staff as they looked after us for all our holiday £50 LE (£5.00 UK sterling every 3 - 4 days.
Tips in restaurants are usually already added on, but that depends on your bill.
Pool lad and beach boy gave £20 LE = £2 sterling for saving our seats.
If you tip well especially if you want information they sometimes take you or get gifts for you from a cheaper place. They are on very very poor wages, a fiver to us means a weeks wages for some.
I have been to egypt 8 times, so if you need any more info, please ask
