"The store is becoming obnoxious." It is rude to you, sticks its tongue out at you? Oh. It expects you to PAY for the goods it sells. Indeed, how rude of it. It should be like your local food store, you just walk in and take goods off the shelf no doubt.
It is a shop not a give-away centre. Maybe grow up and get a job to pay for the goodies you want or ask for them as presents from your mummy.
