I'm sure everyone will agree the golden rule of "birth-bathing" is leave no trace, regardless of your exact techniques. ideally though you'll have access to a private bath with a locking door. I always arrived extra early to be sure I avoided anyone else just to be on the safe side. I had the luxury though of my company moving to a new locale with a shower. man that was the bees knees. like heaven, complete with a boiler room to dry my stuff during the day. they even offered to buy be a locker, but I declined saying if they didn't mind me hanging my stuff in the boiler room, I didn't either. I kept extra food in the break room cabinets and fridge and extra clothes in a box under my desk. I could dry my light and charge them at my desk. man that place was freakin' a commuters heaven. dam I miss that place.
