kind of like "come and play guitar at my bar without pay for the exposure"
So more like "come play at Max's Kansas City without pay for the exposure" -- tons of bands would have jumped at the chance.
It's just that not all influencers have equal reach (and not all businesses need the extra promotion. Nike can always sell more shoes, but an ice cream stand might have to push people away if they have too many customers, as there's so many a person can serve).
