The business owner said it was her 'policy' to add an additional $20 on top of the normal cost of $35 when someone was over her normal size eight limit.

The exchange began: ''Hey girl! I noticed you didn't have a price list on your insta and was wondering how much for the 1 hr express spray tan.''

The owner replied: ''Hey hun. It's $35 for a 1 hour express. I just had a look at your Instagram and I'm just wondering what size you are??''

The confused woman wrote back: ''Oh haha, I'm a size 10-12 AU why is that?''

She replied: ''My regular clients are a max size 8. It'll be $20 extra as there's more surface area if you know what I mean.

''If you don't want to pay a $20 surcharge maybe lose a little.''
