Here baristas were mentioned in some of the comments.
Iâ€™m reading â€œThe Fallsâ€ by Ian Rankin at the moment, and have come across this:
â€˜Not often I see you smiling,â€™ his barista said as she made him a double latte. Those were her words: barista, latte. The first time sheâ€™d described her job, sheâ€™d pronounced it â€˜barristerâ€™ which had led a confused Rebus to ask if she was moonlighting. (page 24)
Obviously, not only is this a Scot (I think we can assume that she is) who is new to the word barista, but also one of the increasing number who are less than fully rhotic!
