Subsistence Scale Rates

The meal allowance scale rates have not kept up with inflation. What's the least effort option for small businesses to allow for higher reclaim rates ? For example, a single light meal at popular coffee shops will now exceed the £5 rate. Surely we can't have every company trying to prove a bespoke rate. https://www.gov.uk/hmrc-internal-manuals/employment-income-manual/eim30240
