Prefererably weekends as I no longer want to get back home late and hungry after an evening weekday punt. There's less traffic on the roads as well.
Also, I want to be her first punter of the day as she should be at her freshest. This has sometimes made booking appointments difficult with the more popular WGs, but I have to deal with that.
Happily, I may retire soon, so none of the above should be a problem.
