So lemme axe you a quextion...on big ticket items (house painting, tile, etc.), do you "tip" the guys doin' the actual labor? And if so, how much is customary? The reason I'm asking is, we're doing some work and dropping around $30K on multiple projects. It's my contention that I am not expected to 'tip' for stuff like this. The Mrs., ever conscious to how hard these fellas work, feels we should provide some folding green. Sooo...point me in the right direction, ok?
