Most guys are takin a cut anyway, be it makin a few bucks or pinchin a few buds cause he knows you dont have scales ( assuming) but proper etiquette is to have a smoke or toss him a bud for his troubles so he knows you appreciate his efforts. Thatll usually translate into a better vibe and even a better deal. Plus if he knows you will 'tip' he is less likely to pinch. I wait till my kids are down for the count before I have a taste too so inviting him in for a session isnt practicle here either. I toss him a bud to show my appreciation since if he didnt drop it Id likely go without cause I cant really bring the family on a run. Ya gotta love delivery!
