How would I get better service?

We collect metal trays. Usually the ones we buy feature whiskey, gin or other alcoholic beverages. For some reason we also bought one big tray with colourful flowers. It is a beauty, isn't it? The English really know their trays. I just have to be careful as we don't have much room for the bigger trays and there are a lot more of these flower trays around than there are of alcohol advert trays...
