Dating cheaper than punting...
Estimate Time = 3.5 hours
TOTAL = $150
*you could very easily spend another 50-100% on all of this (more expensive drinks & meals, restaurant, etc and/or more consumed + go to Gold Class movies if you're really looking to impress), or less if you're skipping parts of the above and on a budget
**when you're dating (whether it's one or several girls at a time), the vast majority wouldn't just be going out on one date per week - the costs will add up very quickly (and unlike punting you won't be as mindful towards this until well after the fact)
***YMMV in terms of the desired expectations/results you hope to achieve from dating (which I assume for the vast majority of us would be to get sex out of our date - and maybe eventually find a long term partner)
A friend of mine is a massive player, currently has 8 girls on the run (don't ask me how he does it as I don't really want to know) - based on conversations I've had with him and the calibre of restaurants, locations, activities, etc he does with his dates (not to mention the social expectations of certain females which is a whole other discussion in itself)... dating certainly is not cheaper than punting, at least from what I can see (not just from a monetary value but also your time).
