Is this racist?

Just been into The Whole Bagel on Upper Borough Walls. Waiting for my order and 2 Asian girls walk in. There are 2 young women making up the order, one turns to the other and says loud enough for me to hear "Let's play eye spy. I spy with my little eye something beginning with yellow" followed by a bout of laughing and giggling.

I don't want to jump to conclusions but it doesn't sound natural to me
