Many of them go to so called 'student nights' in clubs and bars because they think they are getting a bargain booze-up. Well, I honestly don't understand how a club can call it 'student night' and charge £8 entry fee. The drink prices might be reduced or discounted, but if you are not too drunk to realise, they are only normally about one pound less than their usual prices. If you are a group of girls, a night out in Mayfair VIP style amounts to far less than a student night; arrive before eleven, and you get free entry as well as free glasses of Grey Goose and cranberry offered to you all night from table service. Bizarrely, the most exclusive clubs can't help but give away their vodka; in China White last weekend, we actually had a 'Grey Goose' fight.
Students cannot seem to comprehend the taxi v tube debate when it comes to getting to and from your night out. The tube usually involves setting off an hour early, walking to the station with barely any clothes on, taking three tubes across London, and then walking from the tube to the club. By this point, you can no longer feel your hands you are that cold, you have sobered up, and you are therefore going to have to buy an extreme amount of drinks as soon as you finally arrive. On top of this, you may have risked your life. It is not safe for drunken female students to be riding the tube at 11pm; the one time I did, I got threatened with a knife at Elephant and Castle, but was too drunk to remember until someone informed me the following day.
With a group of you, a taxi is likely to cost only around a couple of pounds each. With the comfort of staying warm, you can order the taxi straight to your door, and can be dropped off right outside the club. You have more time to pre-drink at home, and have therefore actually saved money, because unlike the tube mob, you won't have to drink loads in the club because you ran out of time earlier.
Sticking the word 'student' on something doesn't necessarily mean it is cheap. Just because you have used your student Oyster card to get to the club, doesn't mean that it is the cheapest way. At the end of the day, student prices in London do not exist and life as a student is expensive. You might as well just do what normal non-students do, because it costs the same price and is often less hassle!
