Nights and weekends free

My cell phone contract ran out recently and I was thinking about the idea that my cell phone has free nights and wekends which is pretty good I suppose, except that there's really no other service or product where you get free nights and weekends. Like if you rent a car, it's not like Budget or Enterprise is going to give you free nights and weekends, or if you buy a guy, Glock doesn't tell you that bullets for your 9mm are free between the hours of 9PM Friday to 8AM Monday morning. We need to see more services with free nights and weekends. I'd like to suggest strip clubs start this policy.
