A Starbucks grooming business focuses on high-end clients who may be more fussy but they are dealing with less of them.  They focus more time on customer service and making the client happy. These clients may, or may not require complicated, technical haircuts... but they DO require a solid haircut, no hack jobs will be accepted.

Customers may proclaim "do whatever you want", which is misleading because what they really want you to do is figure out the most flattering haircut on their dog.  High end clients vaguely expect you to magically know their preferences and ideals. When these customers have healthy boundaries they respect your time, and your schedule. They tend to work jobs where they are under a lot of time / pressure so luxury or convienant grooming options like Mobile, start to finish cage-free or grooming where their dog can go to daycare beforehand is generally best.

Depending on location I'd assume a shih tzu haircut would be $55 - $85 at this salon.

We all know these shops.  The chop shops.  The "sure you can come in now, or later, or whenever" shops.  The area's "oh God tell me you didn't pay someone to do that to your dog" shop.  Now, if this is your business model please remember it is not realistically a sustainable model.

McDonalds can sell a cup of coffee for $1 because they're trying to get you to buy other things.  Their $1 cup of coffee is called a "loss lead" which means they lose money on one item to get you in to hopefully buy more items.  If grooming is your main service, having a loss lead grooming operation is never going to last.  When you're grooming 2-3 dogs compared to Dunkin Donut's and Starbuck's one dog, you are burnt out waiting to happen.  

Petco and Petsmart use their grooming as a loss lead to sell their dog training, food and other retail.  That's how they can afford $10 - $15 bath specials.  The ONLY way this works is if the groomer is a Hobby...

Starbucks.  Dunkin Donuts.  Mcdonalds.
They all sell coffee

The product is the same.  The branding, ideal client and price point is totally different.

McDonald's coffee is known as "surprisingly good" for it's price point and the fact that it's, well, McDonalds. Hungry commuters or weary travelers can get a cup of coffee, a breakfast sandwich...
