I'm traveling from Peru to New Zealand and I have some leftover Soles. I'm curious if I were in a coffee shop or a restaurant: how would my server react to a tip that includes a foreign currency?
To be clear, I would still leave a proper tip in the local currency (NZD in this case), but I might add a few Peruvian coins/bills "for fun".
Would this sort of thing be appreciated, should I not bother, or maybe does it depend on the situation (e.g., tip jars at a coffee shop work differently than tipping your server at a restaurant)?
