Commentary for Berakhot 46:15

אמר ר' יצחק הנכנס לסעודת קבע חולץ תפיליו ואח"כ נכנס ופליגא דר' חייא דא"ר חייא מניחן על שלחנו וכן הדור לו

R. Isaac said : Who is about to partake of a regular meal should first divest himself of his Tefillin and after that enter. This is at variance with the opinion of R. Hiyya, who says: He leaves them upon his table, and thus it is becoming of him to do.
