The high street baker Greggs are to reopen 800 stores on Thursday for takeaway only and the stores have a new look with floor markings and Perspex screens.
Staff are to wear protective clothing and there will be a reduced menu to help with social distancing in workspaces across all stores.
The sausage roll maker has warned sales could remain subdued because of fewer customers allowed in the stores at any one time.
There will be a proportion of staff that “will remain furloughed until sales levels begin returning to normal,” due to the expected decline in sales.
Greggs said in a statement to the stock market on Tuesday, “We are not able to predict the impact of social distancing on our ability to trade or on customer demand.
“However, our capacity to operate will be restricted by size of shop and we must anticipate that sales may be lower than normal for some time.
“This will require us to maintain a proportion of our colleagues on furlough, either fully or partially, until sales levels begin returning to normal.
“In anticipation of lower sales, we have limited our initial product range to our best sellers and therefore a number of our manufacturing operational teams will remain furloughed until demand reaches a level that justifies the addition of remaining product lines.”
