Great post! Although I do disagree with the 'slightly better form of masturbation' comment - once you've factored in cost, I'd say it's very much a worse form of masturbation
To add to the 'discount or no discount' debate - I always ask for discounts with WGs I've sene multiple times and always got them. Is this because I'm such an amazing greek god of a guy? No, I think it's because I'm polite and reasonable about and it and, most importantly, I'm not a demanding punter - if I spend 2 hours with a girl I'll still only pop once. So I think it's a trade off - someone who is getting their full money's worth, as it were, is likely to find it harder to get discounts from a WG than someone like me who the WG knows they're going to get a soft time with and will therefore be more likely to accept a discount. I appreciate that reads like I need my head examining but that's how I choose to spend my cash and that's my theory. It could well be completely wrong
