To think that my employers could do more in this situation?

We have received an email today telling us that there will be no water in our place of work between 10am and 4pm on Wednesday.

We have been advise to fill bottles and jugs before hand for drinking. Not sure how we are supposed to handle hand washing but we do have some of that antibacterial gel...
However when we need to go to the bathroom, we have been advised that we need to walk to the nearest shopping centre - which is five minutes walk away. It doesn't sound like a lot, I know, but if you are suddenly bursting for a wee...or it's raining again...!

Essentially every bathroom break is going to take fifteen minutes - five to walk down, five to walk back, queuing time and hand washing etc...
Also we are all customer facing so we cannot just 'pop out' for fifteen minutes whenever we fancy it!

AIBU to think that my employers could have arranged a portaloo for the day?
WIBU to return from every bathroom break with shopping bags/takeout coffee cups etc?!

I pee and poo more when on my period.
