I'm not going to get into the why's at Starbucks, but I worked retail years ago and one person insisted on having a standing mat, and I tripped over that thing -all- the time. Just get more comfortable shoes. As ugly as Crocs type shoes are, my back pain disappeared when I started wearing them. They don't -have- to be gaudy, I wear the Santa Cruz often which just looks like a typical loafer. They also make 'work shoes', which are apparently loved by nurses...
