I used to work in a waterstones that had taken over an ottakars (guildford high street), so there was a bit of tension, like early voyager when the marquis and federation had to join forces. Waterstones was considerably gloomier and serious back then, sometimes you would open cupboards to find photo collages of happier ottakar days. Also had vestiges of ottakars everywhere, remote control life size dalek in the kids section (controlling this was my career highlight) and Captain Haddock looming over the stair case
