Often total nonsense on this account but racing people who don’t know it’s a race is a legitimately good game. So many opportunities to play. Traffic lights, escalators, station concourses etc. Losing to someone who didn’t even know they were playing leaves a really sour taste.
Was racing a woman through airport the other day, she didn't know it was a race of course. Rules are you cannot run but use skill so I was gutted when she got the lead due to my schoolboy error in choosing slow security queue but I punched the air when her bag got searched.
