Soundbar is shithouse. Im in there and you have to work your arse off in the soundbar. You have to do a bit of everything like work a register, work stock and help customers at the same time. It also doesnt help when you have a tight store and you are the only person in there all Thursday night...
You can travel while studying. I went to Thailand at the start of the year (recommend it by the way) and am going to Vietnam, Singapore and Indo at the end of this year. Three/four months off is plenty of time.
