Some wait all year for their birthday, others wait all year for Christmas, we here at Triple M wait all day for this: 7/Eleven's BYO Cup Day.
It's the glorious day where the servo/convenience store chain open their doors and allow you to fill any form of hollowed item with delicious slurpee.
Unfortunately there are rules so you can't go and take a water tank to your nearest 7-Eleven.
Whatever you filling up can’t exceed dimensions of 23cm (width) x 26cm (height), has to be watertight, has to be clean and it’s one cup per person.
Consider this a public service announcement.
