Redundancy.

OK, so this isn't exactly momentous, but look at the opening hours of B&Q in Holywood:

Store Opening Hours:
Mon-Wed:     08.00-20.00
Thursday:     08.00-20.00
Friday:     08.00-20.00
Saturday:     08.00-20.00
Sunday:     10.00-16.00

This sort of thing really bugs me. Part of me feels that there must be some reason for it, and then I get quietly driven mad trying to figure out what it is.
