Things you should avoid over here in Doha (at least in the summer) is getting up late on Fridays and having a shower.

Of course you can get up late and smell like a skunk for the rest of the day, but for those with hygienic attitudes I'd recommend not to take your shower later than 7 in the morning.

As usual over here most houses have got an outside reservoir for water, mainly installed on the roof. Automatically filled by the local water pressure this reservoir keeps some pressure even when the water supply should accidentally stop. But it is exposed to the sun throughout the day.

Sunrise over here is around 5 in the morning, from then on the natural heater does its best to increase the temperature of the water tanks on house roofs.

My experience today, gotten up very late and trying to have a shower around noon, was that for a short moment the shower was still refreshing, using the cold water which was still stored within the pipes, but suddenly the temperature went up to hot. And the tab was opened in "icecold" position only.

I knew about it from earlier experiences, but I hope that I learn quickly. And remember the next time.

Hah! Know that from holidays in Dubai.

...by the way: Two young guys from Saxony (hehe) had the same problem, went to the reception and said: "We are sorry, we have a problem with our dusche."
