Bob walked past a restaurant and saw 35% of their tables are empty, so they are reasonably busy, but have plenty of open tables.
He asks to be seated as a party of one, but is told in a most palpably disingenuous manner that they are fully booked, and, upon challenging this, that all of those open tables he sees are in fact "reserved."
The front of house guy shouts something back to the manager in Bengali, and the manager mutters back in English quite firmly that they have no open tables for a party of 1.
Clearly this implies that they have tables available, which they would be willing to seat a walk-in party of two at, they just don't wish to "waste" it on a party of one.
This would seem to unintentionally have the effect of sitting on those who are not married and thus single, even though the motivation is clearly profit driven. Unintended discrimination as I understand is permitted by the Equality Act 2010, insofar as it is motivated as a proportionate means of achieving a legitimate aim, however, this must not be simply increased profits if it is not combined with some type of other concern than sheer profit.
Is the restaurant's conduct lawful?
