The managemnt of CityMall told sue to make reply as soon as possible. They also told her if they refused to take up the offer, the management could modify the floorplan for Next Pte Ltd so that the shop would be cut off from the main flow of customer by building a smaller new alley leading to her shop. Yesterday, the management of CityMall told her that the modified floorplan has been approved and ask her to make up her mind soon as the shop space at new block with good location has been selected by other business. Advise Sue.
请问这个案件的issue是什么? 他的offer是 invitation to threat吗? 然后他有没有vitiating factor? 求帮忙 ><
