But the Govt support has been pretty impressive. They'd get between £10k and £50k business rates grant, plus being able to furlough their staff, plus self employment income support grant, plus government backed low interest loans. No other country has come close to that level of support.
They might have qualified for some business rates grant to cover a small proportion of their income, definitely wouldn't as a business have qualified for the self-employment income support, and quite likely couldn't get a loan (and may well not have any credible way to pay it back for a long time now.
They may have been able to furlough their staff, although the staff are unlikely to be well-paid, so the fact that it's only 80% support would hurt them a lot. The staff may also be casual and relatively short term, meaning they lack the employment history or average hours worked to get a decent furlough payment.
The government support hasn't been bad, although it's actually about average for Europe rather than being world-beating, and it's certainly not anything like 100% of costs. Plenty of business haven't made it through lockdown, and even more won't make it through a long slow loss-making reopening. You have to unfurlough your staff to open, and once the grants and loans are gone, they are gone.
Suggesting that the government package was plenty kind of implies that it is these folks' own fault for something not being able to keep their business afloat, which really makes it even worse
