There is a widespread problem I see - not particular to PayPal or Starbucks - that many companies feel they make enough money, so they don't need to do better.
I expect PayPal could promote itself to brick-and-mortars, but PayPal's marketing people don't feel that they need to, because PayPal makes plenty of money.
Most brick-and-mortars make enough money for their staff to be happy, so they don't look into how they could increase their sales by accepting other payment methods.
This might seem OK but "making enough money" is one of the factors than enables the lean and hungry to come from out of nowhere with a disruptive technology.
