D Wetherspoon is the latest chain to suffer with shortages as they have been unable to serve some customers toast.
Some customers aren’t able to have toast because of the lack of bread.
Their breakfasts make up a significant proportion of the sales.
One customer, who visited one of the Bath branches, told trade magazine The Grocer she was told the problem was down to a “shortage of drivers due to Brexit”.
A spokesman for Wetherspoons said: “A supplier of bloomer bread to Wetherspoon has had labour difficulties at its production facility.
“Thirteen breakfast menu dishes have bloomer bread as part of the meal. Eleven other breakfast meals are unaffected, including meals which have breakfast muffins, breakfast wraps and eggs Benedict.”
Wetherspoons founder Tim Martin, an ardent supporter of Brexit, said the shortages were mainly driven by industrial action in recent weeks by drivers and warehouse staff acting on behalf of Heineken.
“Strenuous efforts are being made to link supply issues to Brexit,” the executive chairman said.
“In this case the main link relates to industrial action, Brexit gave the power to the UK Government to allow more HGV drivers in, should it choose to do so.
“There are supply chain issues in many EU countries following the pandemic.
“It has been widely reported that there are shortages of 400,000 HGV drivers in Germany, France and Spain, for example, and Germany, in particular, is struggling with major worldwide supply chain issues.”
