Partially the players fault, teach them to never rely on unknown stringers and keep that 12-15 racquets strung coming into the event.
The supplied stringing service does sound like disorganised hell, but not unexpected for a new event location. Not even the stringers fault. Lack of planning and oversight from the event organisers. Should've brought in qualified MRT with tournament experience to oversee the stringing room? operations. Then have him use his contacts to select a few experienced proshop employees and dedicated multi lingual front desk service attendant to free the few stringers from mundane common tasks.
Old adage comes back, get what you pay for.
Was there a language barrier?
