Hmm...this is an interesting question. On the one hand, I want to say true, because, coming from one who has worked quite a lot in customer service while going through college, you really realize how hard it is once you do it. In that sense, it's definitely a "don't judge someone until you've walked a mile in their shoes" kind of thing. On the other hand, some people just aren't cut out for customer service. Not that it's a bad thing, but there is a lot of pressure in some retail and food service jobs that not everyone can deal with (for one reason or another, like they would never stop blaming customers and not themselves for the difficulty of the work), in my opinion, and for those people I don't think it would change their attitudes towards those in the customer service industry. So, yeah, I'm on the fence, but it's definitely something to think about!
