Interestingly, the fridge closest to the entrance had cans on my last visit. The 2l bottles were still present further down with the rest of the drinks!

I assume the AC/HVAC isn't working. Last Monday (8th) I was in there before the last Heathrow flight around 18:30. It was unbearably warm. In fact 2 people left the lounge not long after I'd arrived, telling the staff they couldn't stay any longer due to the heat.

Plus, the closest male bathroom was out of action, so it was a long trek to the others behind the 'restaurant' past the bar.
