Hmmm .. On Sunday I returned from Sharm on a Thomson flight. They made an announcement that they had very little ice for drinks on boards as they weren't allowed to load the local (i.e. Egyption) ice due to health & safety regs.
And then ...
Later on in the flight I took my water bottle back to the galley area to get it refilled, I thought they'd fill it up from the tap. The CC opened a bottle of water, poured it into my empty bottle and gave it back to me.
WTF? Maybe if she'd just given me the new bottle I would have had to buy it?
