You got me started. People need to queue for 2-3 hours just to get into a toilet. Even if there is no urgency to use it, people still need to prepare themselves for the day ahead. If anybody needs to use a toilet (having arrived late in the night after long walk from Arafat), they may as well forgo doing any ibadat during that auspicious night. People spend the night on the road, sometimes parked close to bank of water taps. By early morning the taps start overflowing and the entire road gets flooded. Stay in Arafat is a breeze by comparison.
