Refused entry before clising time 17:30

Clicks @ checkerscentre in york street George WC close their doors to customers @17:20 even though their closing time is 17:30. Today I asked if i could come in to get something quickly, it was 17:26 and the doors were closed. The lady at the door asked her supervisor if i may be permitted, but i was refused entry. This has happened to me at this clicks only on numerous occasions, they just dont care. At 17:30 they can be seen leaving the front door with their personals with lights already off. Cctv footage will be able to confirm this. I will never sit my foot in this clicks again and will spread the word as i am not the only one that is unhappy about this. Im just the only one that saud something.
