If someone have 100 million in the bank and he drop 20k, why does it matter? Certainly doesn't matter to him. It matters to you because it's enough to make you care. It's all relative my friend. The $4.80 you pay for the coffee every morning is loose change to you, to some poor kid in Africa it can probably feed him for a week.
Who knows right? maybe this punter is loaded and the jetty he rents in darling harbour cost twice as much on a monthly basis. So why not?
