yesterday i bought a croissant inn the bakery and when i paid they gave me the wrong change . wow thats annoying . but i hope they gave you more than you were supposed to get back not the worst part is that cashier insisted i had given her $ 10 when i was sure it was $ 20 . wow thats annoying . but i hope they gave you more than you were supposed to get back i had to speak to the manger to get my money back . you should call and ask to speak to the manager . maybe they will give you something to make up for it i did and he gave me my money but nothing else .
