On noticing the word 'Esspresso' in an establishment, I tentatively suggested the removal of the supplementary 's'. The following conversation occurred.
Me: Looks like you've got a spare 's' on your spelling of 'espresso' pointing at sign
Staff Member: Oh yeah
Staff Member: Well on the tills it says 'Expresso' [gives pained expression]
Me: Ouch! I hate that one
Staff Member: Sometimes its not worth getting too bothered about things that pacific.
