Too many people in a business when you open

I actually think the large number of customers showing up to a newly opened business is a bug. When I first played around with the retail system some years back I remember only getting five customers max in my store, once I purchased advertisements and unlocked perks more customers began showing up. But now when I start a new retail business I tend to get quite a large number of customers from the get go, making purchasing advertisements kind of useless.

As for managing the large number of customers, I wouldn't worry about making all the customers happy, just focus on a select few and leave the others alone. If some customers get upset and storm out oh well it is what it is. Managing a large number of customers becomes easier as your business progresses.

Can you hire employees? I know you can with vet clinics. My employees help quite a bit. I've also brought family members who pitched in and helped serve customers.

Thanks.

I don't think there is any way to lock out new customers from coming, besides locking the doors, I do know that shops have "curb appeal". The better decorated and the more signage you have the more customers will come to your shop.
