I think you get the odd one or two difficult to deal with persons at the border. Not sure what 'people like you are' but we Brits are treated a lot worse dunnunda. My very worst experience was my partner's gran being treated like dirt entering through SYD when she was almost 90 and suffering from dementia. Actually being shouted at. Welcome to Oz, ey? Well over a decade later the other half still tears up talking about it.
Just like you we have a right to protect our border and if the odd little questions here or there annoys people then that's just tough.
