Visited them a month or so back. It's not really a high street type customer facing business, more like a small warehouse geared toward online business.
I think I got there around mid morning and it seemed to be all hands to the pump packing orders for delivery to online buyers.
However, at least one staff member found time to help me out and I left there fairly happy with some well chosen shrimp.
Regarding the packaging issue. I don't really think it's fair to complain too loudly about how much packaging is used by online businesses. Their priority is to get your order out to you undamaged, it'd be commercial suicide to do anything else. Unfortunately, given the carelessness of our postal service and couriers, they have little choice but to over package items, especially livestock. So they're kind of stuck between a rock and a hard place. Plus, there is also the environmental impact of throwing away damaged goods to be considered, so that probably goes some way to offset the amount of packaging used.
