Nomad Travel Tips:
A day wallet is one that you use just for the day. It is sacrificial if it needs to be. So you keep only a day's worth of cash in it, and no credit cards. Your main wallet is kept snuggled secured away and not used in public. So if some criminal is tracking you and actually steals your day wallet its not catastrophic.
Just because it’s not normal to you doesn’t mean it’s not enjoyable to meet and talk with new people, and have a bit of fun. I’ve had plenty of barters that didn’t meet agreement but still walked away on friendly terms. I’ve seen fellow travellers pay a higher price after bartering a seller down just for the fun of the negotiation.
