I worked in a school where the only exit was past a church that was used for gypsy funerals. There was never any trouble but they did tend to block the exit home - so we were advised if possible not to plan out exit home at that time. It was just a sensible thing to do. Most teachers tend to work late so we were advised to leave promptly for once if the funeral was after school leaving times. A number of our students were involved in the funerals as it was a school that had a number of gypsy students - and exeats were granted as part of our understanding of their culture.
