A recognisable uniform means a recognisable brand. The more ways a customer can connect to your brand, the more they will remember to come to you when they need your services. A strong uniform can also act as a fantastic advertising strategy, as potential customers may have access to the brand while they are on the move.
If a member of staff is wearing a uniform, it is likely they will more aware of their actions as they are easily identified by their uniform and name badges. Being more aware is likely to result in more positive behaviour, which will create a positive impression of your company and ultimately will influence how your customers feel about your brand.
