Has anyone else noticed this?

On our last trip to the Philippines, I did try to be careful about what I ate - and also what I drank too.

I made sure everything was cooked, hot and clean. The water was always bought cold from a shop and the soft drinks, ie, Sprite mostly - there was a lot of this - was also brought from the shops.

But I did notice that once you opened the bottle of water, you heard the click of the plastic breaking then the water was so full it always came over the top.

Do you think these bottles are being refilled and then sold on as new? It was too late once you'd opened the bottle to check to see if it was new.

Am I going mad, I wonder? or just nothing else to do.
