Slightly different visa question

My bird is about to apply for a visa, only for 2 weeks in the UK. She wants to say she works as a hairdresser in a salon, however, the truth is she actually owns a successful bar and is not short of money. Her friend who owns a travel / visa shop has convinced her on this action, saying anything to do with a bar will be turned down.

""I understood all about what you have said and XXXXX situation as well. UK Government would not accept any kind of work about Bar even she is the boss for a bar. and about the job should not relate with any bar.""

I thought as she owns a bar, ( which is why she only wants to come for 2 weeks ) and it earns good money, it would look better than being a hairdresser. I have never given her any money, in fact, she even pays for my food. lol.

Are bars totally poison in the visa direction ??

well don't mention the job . just show the money and more importantly the collateral !

if the bar is successful as mentioned that is.
