Morrisons is a British supermarket company. It has large food shops in many towns in the UK, the kind of place you go for milk, meat, and a weekly shop. In 2004 it bought Safeway and became one of the biggest supermarket groups in Britain. In British English people say “I’m going to Morrisons” the way someone in Taiwan might say they are going to a well-known chain. It is a proper name, always with that capital M, and in everyday speech it means the shop, not a family sitting at dinner. You will meet it in UK news, price comparisons, and “where shall we get bread?” talk. It is not a Taiwan brand; students here do not see the shops. Though actually, the name is just the Morrison family’s shops, with an -s, not a grammar plural you need to worry about.
