Back in the day, I used to work for a company organising freshers fairs and it was always about the free Dominos! Also, one of the most memorable freebies was a spatula from Wilos (RIP).
On an advise front, I have very few regrets but the biggest is not following through with all of the societies and clubs I signed up for...If I could give one peice of advice to past Paul it would be "dude, actually keep playing rugby, do go to that Warhammer club and actually attend knitting club as it is a vital life skill!"
