Sabka Dentist — Wrong consent form

Address:

Shop no.4/A home town near ayodhya society near alok flat GST CROSSING RANIP 380081

I visited sabka dentist at new CG ranip, and I was shoked when they asked to fill consent form where personal details are required, in your personal information section they are asking personal details like income etc. And in consent form it is clearly written if something goes wrong and any problem happens even like haemorrhage sabka dentist is not responsible, moreover it was written they can use my information for marketing purposes, send mails, message videos etc, I couldn't understand the reason behind these terms specially asking family income, staff is impolite and it feels like you are visiting government hospital.
