We have always tipped taxis, bar and restaurant service but after reading this forum realise that the norm in the US is also to tip for maid service. We are coming to honululu in June and assume we should tip $5 a day. Is this correct, but more importantly how do you do this? Just leave the money out with a note or on the kitchen bench? Apologies if this is a dumb question but this is not standard practise at home.
