One time I tipped an artist I hired for a commission and they cried. They said I was the first person who had ever tipped them in their almost 2 years of selling commissions. They were so shocked that I liked their art enough to leave a tip. They said they never felt like their art was that good, or that their customers weren’t really happy with their art, until that moment. So, seriously, tip the fucking artists you hire for a fucking commission. 

Wouldn’t that be kinda like buying a ticket to a concert and then tipping the band?
