What matters is which position you prefer and which position can develop you more.
The quality of a position depends not only on the current salary, but also on the future development of this position and the skills you can acquire in this position.
For the welcome post: the physical requirements are slightly higher than other posts. For cashier positions, more serious, meticulous and responsible personnel are needed. After all, the money problem is more serious.
Are you going to practice at present? What do you want to do after the internship? Do you also do some basic services in restaurants and restaurants? If you just want to do basic services, the salary of welcoming guests is undoubtedly higher-but this industry is a youth meal-have you ever seen a 30-year-old welcoming guest?
It doesn't matter whether the boss thinks it's good or not. To be honest, I don't think the boss will pay special attention to a certain position or position-unless the position or position is very important and the individual's emphasis is different, which leads to the different positioning of each company. Some five-star hotels welcome guests beautifully, and the salary may be higher. Some small restaurants pay attention to the cashier's skilled work, quick collection, quick checkout and accurate group calculation, so the cashier's salary will be higher.
I still suggest you study more-improve your value. I hope it will help you in the future.
