Dimples make the glass easier to hold when wet. Because it is wider, it's not so easy to get a firm grip. If you drop a jar or 'sleeve' as they were known in Dorset, you have to buy another pint. It's a lot harder to drop something with a handle.

They are on the decline for storage reasons. A bad staff member can stack upward of 20 glasses (bad because the pressure cracks the bottom ones of the pile and Health and Safety would scream and faint if they saw you doing it... all that glass you could trip and fall with....), but jugs can only be held in groups of 5-10. They don't stack, so have to have lots of shelf space. They are a pain to put through the sloshy hedgehogs and the handles collect dirt. The only advantage to the bar staff is that they don't break so easily, so you can't get glassed by one.

LTS - who always used a jug until moving up north to London. Can't get them for love nor money now.
