People in the UK are used to B4 (HAVE) excellent customer

People in the UK are used to B4 (HAVE) excellent customer service in the shops and are not used to doing things B5 (SELF) . We saw a TV programme about IKEA. The main idea of it was bad customer service, inconvenience customers suffer putting furniture together. All B6 (THIS) complaints looked ridiculous to us. Manuals from IKEA on assembling'furniture are so clear that a child can do it. They contain no words at all just B7 (DETAIL) steps on how to assemble it.
I remember B8 (ASSEMBLE) hall furniture in our apartment in Russia. 30% of holes were not matching and I had to drill holes with a bigger diameter or at different angles to put pieces together. The mirror was much B9 (BIG) than the place for it and I had to drill new holes and cut metal shelf holders to make everything fit. It took me a week. I am sure that many Russian people have the same 'nice' memories about assembling furniture.
We bought a bookcase with several shelves in British IKEA once. 'Cheap and cheerful' as people say. I assembled the thing in 15 minutes. Every hole was exactly in its place, it B10 (BE) easy to assemble it even without instruction manuals just using common sense. So we are very pleased with shop services here and don't understand why people complain.
