I am sure there are various idioms for this situation. Here are just a few:-make a rod for your own back (do something likely to cause difficulties for oneself later)you've made your bed, now lie in it (something that you say in order to tell someone that they must accept that they will suffer as a result of something bad that they have done)shot yourself in the foot (to say or do something stupid that causes you trouble)So you have heard that Ipswich is getting a Pret - and that it will be located at the Grimwades building shared with a new bank (believed to be Metro)? Well, that might not be the case...Everyone (almost) that didn't want a Next there, wanted a restaurant or cafe to bring life to the Cornhill after being told the boring English town square should become a piazza or plaza (same thing, different language) including al fresco dining... the council then did the honourable thing and decided no, it shouldn't become a restaurant and must stay as a shop. It refused the application. It is believed an planning application is required before Grimwades can become a bank and an slightly upmarket Greggs. Some Prets do what Greggs and various other companies do, and perfectly work out their floor space so the majority is A1 retail - despite acting in part as a restaurant (A3) and a hot food takeaway (A5) - it is a loophole so they don't need a change of use which would likely get refused.[IP/16/00738/FUL] Change of use from A1 (retail) to A3 (restaurant) at 2 - 6 Cornhill for Applicant Mr David Revill through Agent Victoria Poole.This application was received exactly a year ago.
