In n Out burgers

Anytime I go to Tempe to race my family and I always stop to eat at the In n Out burger. There aren't any In n Out burger joints in New Mexico, so it's a treat for us to eat there. They have some really delicious food!

While at Tempe's In n Out burger there are always dozens of birds swooping in for dropped or abandoned food at the outdoor patio. While there relaxing, staying off my feet preparing for my race I enjoy feeding the birds french fries. Last time I was there I saw a sign at the In n Ouyt burger saying, "Please don't feed the birds for health reasons". That made me wonder.... if In n Outs food is so unhealthy that it's bad for wild animals why am I eating it?
