Urban myth.
When there was no furlough scheme, Martin, not unreasonably, pointed out that if they were closed indefinitely, then they wouldn't be able to pay staff, but if that meant that staff left to take up other opportunities then they would welcome them back with open arms. Twitter / Facebook etc started screaming that this was outrageous, apparently ignoring the fact that if they continued to pay staff while they weren't allowed to trade they would go bankrupt and there would be no jobs for anyone to return to.
As well all know, the government introduced the furlough scheme and Spoons furloughed their staff. Despite actual living Spoons staff pointing this out to people on social media, the legend that evil Tim sacked his staff continues.
Funny place, social media.
