<human>: Can you summarize the given text in a few sentences?

Over the course of the last few weeks, I have been applying for management jobs at different restaurant chains. Recently, I went through a few rounds of interviews and received an offer for employment. The problem is, the company that Im working for is great and I would love to continue working there, but the pay is absolutely garbage and theres no room for negotiation. Normally, id be jumping for joy and willing to start after giving my 2 weeks, but heres my situation:

This is not my ideal company. While becoming a manager is a step up in my career and im sure the experience I would receive would be valuable, I would be much happier with other companies (including my current job). I received this job offer a few days ago, but im currently interviewing for more exciting opportunities as I type this, including ones with higher pay (just got done with one interview and have a different one tomorrow).

How long can I string this employer along before giving them an answer on their offer, and is there any room to negotiate a salary higher or would they tell me to go pound sand? Do employers ever revise their offer?
<bot>: Happy where I am right now, but way underpaid. Want to take step up in career but dont want to take a lowball offer.
