A Dumbarton coffee shop had its customers in pieces this week with its wise-cracking sign which takes a dig at US President Donald Trump.

As has been widely reported, the former reality TV star has vowed to build a 2,000-mile wall along the US-Mexico border at a cost of around $20bn, as estimated by the department of homeland security.

And this week a Dumbarton cafe shared a joke at the expense of the world leader with a note on its sandwich board promoting its traditional tasty offerings.

The sign outside the Levengrove Coffee states: "Burritos so authentic Donald Trump would build a wall round them."
