The so-called 'purple pound' - the potential money to be spent by disabled customers and their friends and families - could be earned by more businesses with more accessible restaurant furniture, pub furniture, shops and entertainment venues.
According to research conducted by the Department for Work and Pensions, access to shops is the biggest obstacle for disabled people, followed by entertainment including concerts, theatre productions and going to the cinema.
Next up is eating out or going for drinks - an indication perhaps that some pub furniture and restaurant furniture is not well suited to accommodating disabled customers.
The solution to this is not necessarily to install seating that disabled people can occupy themselves, as many of those who are in wheelchairs may prefer to remain in their chair for mobility reasons, and many others are likely to find that any normal chair can serve their needs perfectly well, as long as they can reach it.
But this is where the problem lies - and the government are urging businesses to make sure their premises are not unfairly inaccessible to disabled people, as this could even be against the law.
As such, venues should keep corridors and aisles clear - which, in pubs and restaurants, could be extended to include a route from the door to the main customer areas, bar, tills and toilets, particularly the disabled toilets.
Mark Harper, minister for disabled people, said: "It's not just about fairness; it makes good business sense to be accessible."
With an estimated £212 billion of income in households with a disabled resident, and one in five customers affected by a disability of some sort, the potential economic benefit is vast.
And it doesn't have to mean extensive alterations to premises, once you have a flat or ramped entrance as opposed to stairs, and adequate disabled toilets and other such facilities.
When it comes to choosing restaurant furniture and pub furniture to suit disabled people, the rule is the same as with any other customer - choose seating that can be installed without leaving insufficient space to move around it.
In the case of restaurants in particular, this makes good sense not just because of disabled customers, but also in order to allow waiters to carry food to the tables without the risk of tripping over a rogue chair.
