No coldrink with meal at Cradlestone mall

Morning. McDonald's Cradlestone mall was a disappointment yesterday around 14:00 when I went to buy my son food after soccer.i was planning to buy more but bought 1 meal with water which I didn't want but forced by circumstances.

They didn't have coldrink and when I asked why the excuse was that they ran out of gas because it was a weekend.

How many weekends do we have in a year and I wonder if every Monday is like that or is someone not taking responsibility. Imagine on the 1st day of the month.during high sales
