The heart behind the new rules is in the right place. Although, most certainly, men shop in cosmetics shops, to buy items for themselves or gifts for others, the majority of customers in such establishments is women. It is self-evident that, in most cases, women are generally more knowledgeable when it comes to make-up as they are the ones who wear it and, in some cases, have been wearing it since a fairly young age. Logic dictates that they should be allowed to stand behind the counter and attend to customers.
In addition to salespeople and customers of different genders, there is also the issue of male managers and female employees. Again, it flies in the face of strict traditions in the Kingdom.
In short, changing what seems to be a small part of labor regulations has unforeseen repercussions that will also demand attention. Like a stack of dominoes, one change will beget another, which will beget another, which will beget another. The road to modernization is a difficult one to travel, especially when it is being mandated by legislation. The question all must answer, in the end, is whether that road will lead to a better, stronger and healthier society.
