BP Kuranda Roadhouse in Kuranda, Tablelands

I have lived in Kuranda for over 7 years and always buy fuel off BP.
I went there today to fuel up my ute and fill up a 200 liter drum. I was refused service when I went to fill up the drum. Asked why I could not fill the drum and was told it was BP'S policy even though I have been doing this here for years.
Went elsewhere to purchase 300 plus liters and will not return to this business.
