my girfriend works in starbucks and she almost always do overtime. For example, she suppose to work till 22:00(shopping centre works till 21:00) but she finish 22:30 or later and always telling me that she had to clean the shop or something. Should i be jelous?

Nothing is going on, the managers in those places are obsessed with hygene. When I worked at booger fling it took a couple of hours after closing to clean up.

It's not a great job...don't be jealous of it, you could ask the manager if there are any vacancies there, if your girlfriend is always having to do overtime then possibly they need more staff.

Jealous of her job? No. You should be mature and not worry about such a petty thing. Being out 30 minutes late is not anything unbelievable and it isn't necessarily doing "overtime."

No. Your girlfriend should be worried about your controlling attitude.

no
