We offer a battery service where I work. A driver will come out and test your battery and if it needs to be replaced, they can replace it - for most vehicles.
This service runs 7 days a week - from 6a - 11p M - F and 11:30a - 11p on the weekends. This is the same EVERY FREAKIN' WEEKEND!!!
EVERY WEEKEND - WITHOUT FAIL - someone will send a battery van request through before 11:30. Sometimes, multiple of people will send them through. Every weekend, I have to remind a floor supervisor that this service isn't offered until 11:30am on the weekends.
