If you are a salesperson in a shop and there is a queue of people waiting to be served, what do you do when a friends pops around to say hi? In Peru it's perfectly acceptable to now have a conversation with that friend. The people in the queue will wait patiently while you have a good chat.
I (David) was in our local market the other day purchasing some vegetables. I handed over the money to the lady for the vegetables. Midway while getting my change a friend of this lady came by to say hello. They began to have a great conversation while I waited patiently for a small amount of change (less than 10c). Soon I began to suspect that I had just made a miscalculation and had already actually been given all my change. Why else would this lady launch into a conversation? So I headed off and to a different part of the market. About a minute later the lady from the shop came running. She'd left her shop to find me and give me the rest of the change.
Friendships are more important than time, here in Peru. We've now gotten to know this lady in the vegetable stall and she stops to say hi to us even if she's in the middle of a transaction with someone else.
