I am not sure what shopkeepers are expecting when they place teeny tiny items on the floor. Do they expect customers to kneel down and browse through them?!
DON'T: When merchandise is stacked atop one another in a glass unit, there is hardly anywhere the eye can stop. There are advantages to a glass unit such as allowing the light through the displays, however the one pet peeve I have about these units is when it looks like products are just crammed in. Very unappealing, where's the romance?
