        Taxicab drivers in Edinburgh, Scotland, are upset about a strict new dress code that says they must wear flannel trousers, a shirt, and shoes.
        Cabbies say the code is too restrictive. Furthermore, they complain that it takes away freedom to wear the national dress—including the Scottish kilt. Cabbie Jim Taylor, of the Edinburgh Street Taxi Association, says that cabbies will go to court if they are forced to follow the dress code.
        Taylor remarks, “Most drivers already dress appropriately so there is absolutely no need for such a restrictive dress code. What if a driver wants to wear a kilt? According to this new code, he can’t. After all, we are self-employed drivers. We are not city employees. It is unreasonable for the government to make us follow a dress code like this. No judge can tell us how to dress.”
        However, Phil Attridge, a member of the city council, disagreed. “We do not think the dress code is strict. Most drivers already follow it. We don’t want drivers to wear jeans or shorts. Dress is important because drivers often go into hotels to pick up passengers—they should be well-dressed.”
        On the issue of kilts and national dress, Attridge added, “If a driver wants to wear some kind of national dress that is not in the code, he or she can ask permission.”
        He said a survey showed that 76 percent of cabbies and taxi owners wanted the dress code. In fact, police officers are already enforcing the dress code, and one driver has already paid a fine for wearing corduroy trousers instead of flannel.
