Comment: Of course KD, the other option would be for the restaurant to simply raise their menu prices a bit and just carry on instead of trying to shame the (lowest paid) employees as the cause.

And if they want to continue being wankers about it, let's see some other honest surcharges added to the bill...like, "$5 to service the company jet" and "$7 for last years vacation in San Tropez".
If you're going to call out extraneous expenses, let's be fair.
