The One With Ross's Tan - S10-E3
Question: I occasionally perform spray tans as a side gig, and the solution usually takes around 8 hours to set. Is there any reason aside from creating a comedy situation that the spray tan salon wouldn't just tell Ross to immediately go home and shower so that his tan won't look so ridiculous?
Answer: None at all. It's played for laughs and that's all. If we really wanted to give it a real-world explanation, we can speculate that maybe Ross stormed out of the tanning salon without giving the staff a chance to recommend a shower.
