I walked pass this shop-lot the other day and noticed the creative “Cash term only” message stuck on the door. This used to be a cafe, one of those that I… you know… let’s just say I am not surprised that they did not last very long.
The (ex-)owner probably thought this message is cheeky, but I reckon it actually left a bad taste in some potential customers’ mouth. If you are running a shop, being able to accept credit card is a basic expectation. Not having that means you suck.
You should be apologetic about it, not bloody claim that “it is for your own good”.
