Door Supervisors need to have good verbal communication, people skills, and the ability to defuse any situation. Be able to look after themselves and the customers in the premises they are looking after. In my experience, height and looking intimidating isn't a key factor in being a good door supervisor. Having good communication skills and being able to look after the customers in the premises is more important.
Having good door supervisors looking after a venue makes the customer experience more enjoyable, gives the venue a good reputation which in turn attracts more customers. We at Spartan 24 Hour Security look for quality when taking on a door supervisor and are very good at quickly spotting a plonker. Talking to someone for a length of time gives you some idea of their character. Then giving them a shift covering a venue and observing how they interact with customers and help defuse situations tell you if they are going to be any good. Not everyone can do this job, some try but fail and end up getting badly hurt.
The best door supervisor I've worked with was 5ft 5ins tall, had a great personality which shone through when dealing with customers. Was very helpful and was on first name terms with a lot of them. He was also very handy if things did get out of hand and was a 5th dan in karate. Spartan 24 Hour Security provide professional, high quality door supervisors both male and female. For nightclubs, bars, pubs, events, concerts.
