This is like explaining colour to a blind man, or civilisation to a Welshman..
Typical English average service would be:
Get seated, wait 5 minutes for someone to show up with menus, wait another 5 minutes for someone to ask for drinks. See someone when food is delivered. Wait for 5-10 minutes with empty glasses of drinks or empty plates until if you're lucky someone might occasionally stop by and see if you need anything then wait 10 minutes after finishing to get someone to bring the bill.
Typical US service:
Get seated and within a minute you have menus, a jug of water and glasses and are greeted with a smile and a request for drinks orders. Drinks come quickly and the person will check-in on food orders, ask if you have any questions or can offer recommendations. Person will keep an eye on the table and if drinks are getting low, or if anything appears to be an issue will come over and see if you need anything without any prompting. Tables are cleared promptly but not too early and the person is attentive, personable and cheerful throughout.
Would be my general experience anyway
