I want Ice Cream

The tap water here is desalinated, well partially desalinated to be exact. As such, it's a bit salty for drinking and cooking with. For drinking water, you have two options.
Option 1 is to buy bottled water. You can get either local stuff or the slightly more expensive Egyptian stuff which is brought in through the tunnels. Actually, pretty much everything/anything comes through the smuggling tunnels between Gaza and Egypt. Apparently a lion was even brought through for the local zoo!
Option 2 for the water, is to buy it in bulk from your friendly corner store. Most of the little general stores (there's about one every fifty meters) have a large stainless steel tank out the front. You pay your money, get the tap, and fill up your large BYO bottle to lug home. These tanks are filled up by water trucks that come around regularly. The trucks, which seem to drive past the office every 20 minutes, announce their presence by playing a Mr Whippy-like ice cream song. All this is making me crave ice cream!
Some friends of Shez's recently immigrated to Victoria and I'm a bit torn as to whether I should tell the kids what the song announces in Australia.
