easyJet are not as ruthless as Ryanair but you should assume 30 minutes means 30 minutes. You're welcome to push the envelope but don't be surprised if you are denied boarding...

The LCC model is very tight on time - they expect the self-loading cargo to be fully ready to board the minute the plane is clear. These guys run a 25 minute turn around schedule (I know this is the first flight but they are just culturally more disciplined than FCCs).

"Customer service" means getting you from A to B cheaply - and that's it!

Having said that, if you know the system and how they work, LCC services offer amazing value. I used to commute from Glasgow to London every week with Ryanair for typically less than £50 return...

It's easy for expense account flyers to sneer, but for point to point it's often more convenient, as well as cheaper.
