I've been on plenty of guided trips in the past six years and have developed some what of a pay scale to tip the guide.
If the guide greets you with a smile and or a joke,he puts you on your two fish,and was fun to be with for that 8-10 hr day and splits the eggs 50/50 then you should tip them around $40.00 to $50.00 bucks.I'm not rich!!!!.If the guide is an average guy,ok to be with for 8 hrs or so,gets ya a fish or two,then tip around $20.00 to $25.00 bucks.
If the guide has no personality,didn't seem to care to much about any thing,was done right at 7 1/2 to 8 hrs,managed to get one fish and demanded all the eggs,then I would
have a hard time giving him the $150.00 bucks,let a lone giving a tip or referring him out to any one else.I don't think there is to big of tip or to small of a tip.It's what you can afford considering the quality of the trip and how much it's already cost you to just get there.Good luck,
