First, increase the prices to be the most expensive in the area.
Second, change the paint scheme on the outside of the pub from a mock Tudor style with fake beams, which is a local landmark, to Army Khaki.
Third, re-brand the pub as a wine warehouse with an illuminated sign.
Fourth, employ an a blind interior designer who has never visited a real pub.
Fifth, drape the "pub" with banners saying it is now a Thai Restaurant.
Sixth, make all the customers invisible to the bar staff.
Result: 50% of the pub sectioned off for the restaurant that on a Saturday night had a grand total of zero customers and the two dozen pub customers having trouble being served by the 4 bar staff who are having a social event themselves at the end of the bar.
Well done Greene King, keep up the good work with your pub improvements.
Note: this was once a busy pub in bed-sit land where people have nothing better to do than visit the pub - that's until the GK decided to go up market.
