Like a Birkenstock, stamping on a human face forever*

From The Evening Standard:

Transport For London staff have been banned from using electronic cigarettes at work because they are too realistic. And customers may also be forbidden to "smoke" them in future, bosses at TfL say.

In an email to staff, the organisation writes:

"E-cigarettes and nicotine inhalers are extremely difficult to differentiate from real cigarettes, therefore if someone uses an e-cigarette or nicotine inhaler in the workplace it might look like they are smoking a real cigarette. This is not the image we want to portray to customers and colleagues."

* I can't track down who first used this phrase, but whoever it was knows who they are and is hereby awarded a prize in their absence.

UPDATE: Having done a bit of internet archeology, i.e. Googling all hits before a certain date and moving that date ever earlier until there's only one, it would appear that the phrase was first used by a US anti-abortion campaigner in 2005.
