People do a lot of things to earn money in Costa Rica. For example, it is not uncommon for someone to board a public bus and hawk food. I don’t think they pay and they don’t stay on long. They must sell things or they wouldn’t keep doing it.
Another curious thing was vendors (and beggars) standing between lanes of traffic selling everything from food to cell phone chargers, toys, sun glasses, etc. The main bridge in and out of San Jose was under construction for a number of months and we had the “pleasure” of experiencing the delays caused by a reduced number of traffic lanes (aka sitting in traffic barely moving…kind of like it is in Austin now). Above are a couple of pictures we took from the taxi at vendors.
