Is it popular in England to put peas in Chinese fried rice?

Well, I've had it with and without.

Sometimes if you order fried rice from a Chinese takeaway they come with peas in it but we don't normally put peas in it ourselves. 

It is popular in a Lot of places as a filler. 

All Chinese fried rice I've ever had in a western country has had peas.

A lot of us don't tend to make that but it's always sold in chip shops, if you are having it plain it won't have peas in it but you can add all different things.
