I remember reading in some article (can't be bothered to google!) that forcing employees to smile etc. (be positive) was considered discrimination. Now I can't remember any details, whether it was just a company or something to do with the government - but yeah you're 100% right: preferring smiling people over unsmiling ones is as racist as preferring white people over black ones. The employer might say, "but my customer base loves smiling people"; but then he can say the same about whites etc.

Anywayz, Great work! Loved every word of this!
