The club also had the option to decline your request for them to stop kicking you in the junk. You took your business elsewhere till they stopped kicking you in the junk. Now, knowing that you were rewarded for taking your business elsewhere once, why should I think you would not threaten to do so again if there was something new that you wanted?
In fairness I think asking not to get kicked in the junk is not unreasonable. You do really need to take into account the severity of the situation and the request being made. A $2 hike in drink prices might in cur some patrons to leave but no where in the amount getting punted in the nuts each time you went there would. Which suffice it to say is what some people are feeling is happening.
