I totally agree with the statement that everyone should have to wear smart clothes for work if they come into contact with members of the public. I think the first reason of all is that human awareness about the education. We need to be respect to the people who contact with us. So that we can make an attention from others and make them concentrate into conversation instead of looking around. Besides, the members of the public will also look up us when they see our smart appearance. For instance, when we get the good notices from other's eyes, it's easier to get into an initiative conversation and both of us have more opportunities to know more about each others. And the last, it make us feel more confident when meet someone else. We will not feel worried about how the people feel about the way we wear on the body. They also find out our respectation to themself, so they will open their mind and share things with us. In short, no rules that force us to wear the favourite clothes when contacting with members of the public. In contrast, it's good for us to wear smart clothes for work.
