I have just got back from my local indoor soft play centre where they tried to charge me £1 for a jug of tap water - when i refused and asked why, i was told it was because they had a water meter and because they sold bottled mineral water. Before i write A Strongly Worded Letter Of Complaint i would be interested to know what the law says about this - I do not want to make a total fool of myself, but it seems to me essential to offer either a drinking fountain or free tap water when you are offering excercise facilities for children? Am i right in thinking that restaurants and cafes are obliged to offer it?I was FURIOUS - what does anyone else think? is this a common problem? thanks!
