Vary Recruitment interview questions

Made my way into glasgow at 8am, spent £20 on public transport and cancelled many plans to attend this interview. I arrived and was asked to fill out a form. I began filling it out only to be asked how old i was, i then replied 17 and was told i had to be 18 for this role. I then asked why i couldnt be told this over the phone and the interviewer just shrugged. Absolute joke of a company waste of my time and money do not go near them they are not organised at all. All the employees just looked at me when i said i was there for an interview.
