I did a bit of travelling with Tinkerbelle. The UK had (at the time) some quite cheap mobile options and I saw an advert for a full fitted out grooming wagon - it was cool.....
Anyway, never had shopping and often not permitted to stay. But always leave for the appointment and collect when done or the collection service was the time they specified.
Nice touch was in Amsterdam, when trainee groomer did the work (closely supervised) and we got a free bow
She wouldn't wear it, so it was attached to her collar! haha!
I;m not much of a shopper for clothes and glitz, but I love gadgets, unusual treats and such. I do understand that there are lots of people that do, though.
Hope it goes well
