I kind of agree with you on the tip thing. I have never understood it. Now before everyone gets crazy, to this point, I have always had decent guides and always tipped. However, in researching guides, many of their websites make a tip appear to be almost part of the deal. The first saltwater guide I ever fished with had an app on his phone to run my credit card since he preferred credit cards over cash. Thought it was odd to enjoy paying fees, but when he handed me the app, I found out why. He had run it all the way to the screen that asked for me to fill in the percentage of my tip. The choices started at 15% although there was small lettering at the bottom that said decline. It's a business. Adjust your prices accordingly and be gracious and humble when it comes to tips.
