Pat,

Because, and I apologize for having forgotten this important detail, the bill at Pineapple Pete mentioned "15% tax".
It's only after I specifically asked the waitress what was this 15% tax about that she told me, "it's service".
Hmmm..... thanks for telling me what it actually is, but what if I didn't ask?

Like I said, businesses should be more upfront and honest about service because at the end of the day, they'll be the big losers when their patrons discover that they've been taken for a ride and they'll post about it on high traffic social media sites.
