People probably don’t have an issue donating $1-5/month to feed someone hungry in another country.
Or to drop a $1-3 donation in the mall at the register when the store is raising money for something (breast cancer week, etc,etc,etc)…
But on your way to the shopping mall (say fashion valley), where you plan on spending money that day, do you bother to drop $1 with the guy/gal pan handling at the traffic light? If not, why not and what’s the difference?
